AB  - The aim of this review was to summarize the data regarding diversity of non-starter lactic acid bacteria (NSLAB) isolated from various artisanal dairy products manufactured in Western Balkan Countries. The dairy products examined were manufactured from raw cow's, sheep's or goat's milk or mixed milk, in the traditional way without the addition of commercial starter cultures. Dairy products such as white brined cheese, fresh cheese, hard cheese, yogurt, sour cream and kajmak were sampled in the households of Serbia, Croatia, Slovenia, Bosnia and Herzegovina, Montenegro, and North Macedonia. It has been established that the diversity of lactic acid bacteria (LAB) from raw milk artisanal dairy products is extensive. In the reviewed literature, 28 LAB species and a large number of strains belonging to the Lactobacillus, Lactococcus, Enterococcus, Streptococcus, Pediococcus, Leuconostoc and Weissella genera were isolated from various dairy products. Over 3000 LAB strains were obtained and characterized for their technological and probiotic properties including: acidification and coagulation of milk, production of aromatic compounds, proteolytic activity, bacteriocins production and competitive exclusion of pathogens, production of exopolysaccharides, aggregation ability and immunomodulatory effect. Results show that many of the isolated NSLAB strains had one, two or more of the properties mentioned. The data presented emphasize the importance of artisanal products as a valuable source of NSLAB with unique technological and probiotic features important both as a base for scientific research as well as for designing novel starter cultures for functional dairy food.

AB  - In order to preserve the traditional manufacturing of white pickled (WPC) and fresh soft cheeses (FSC), well-characterized autochthonous lactic acid bacteria (LAB) with advantageous characteristics were applied for the production of the cheeses at small industrial scale under the controlled conditions. Selected LAB for design of defined mixed starter cultures belonged to Lactococcus lactis ZGBP5-9, Enterococcus faecium ZGPR1-54 and Lactobacillus plantarum ZGPR2-25 for FSC production and to Lc. lactis BGAL1-4, Lactobacillus brevis BGGO7-28 and Lb. plantarum BGGO7-29 for WPC production. A sensory evaluation indicated that the cheeses obtained by inoculation with selected autochthonous LAB are similar to the traditional cheese and received the best scores. Viable cell counts of LAB used for the production of both type chesses was high, over 10(6) cfu g(-1). High viability of the surveyed strains was supported with PCR-DGGE, which confirm the retention of selected LAB strains as starter cultures in cheese production. Next, PFGE analysis showed that each single strains, selected in particular cheese mixed culture, revealed unique SmaI PFGE pattern that could enable efficient discrimination and monitoring of the strains in industrial process. As some of the selected LAB strains are attributed as potential probiotics, produced cheeses could be considered as functional food.

AB  - Background: The bacteriocin LsbB targets a membrane-bound zinc-dependent peptidase. Results: The structure of LsbB was resolved by NMR. The C-terminal unstructured domains of LsbB and several other related bacteriocins were responsible for receptor binding. Conclusion: A subgroup of leaderless bacteriocins has been found to share a similar mechanism in receptor recognition. Significance: The study highlights the structure-function relationship of LsbB. LsbB is a class II leaderless lactococcal bacteriocin of 30 amino acids. In the present work, the structure and function relationship of LsbB was assessed. Structure determination by NMR spectroscopy showed that LsbB has an N-terminal -helix, whereas the C-terminal of the molecule remains unstructured. To define the receptor binding domain of LsbB, a competition assay was performed in which a systematic collection of truncated peptides of various lengths covering different parts of LsbB was used to inhibit the antimicrobial activity of LsbB. The results indicate that the outmost eight-amino acid sequence at the C-terminal end is likely to contain the receptor binding domain because only truncated fragments from this region could antagonize the antimicrobial activity of LsbB. Furthermore, alanine substitution revealed that the tryptophan in position 25 (Trp(25)) is crucial for the blocking activity of the truncated peptides, as well as for the antimicrobial activity of the full-length bacteriocin. LsbB shares significant sequence homology with five other leaderless bacteriocins, especially at their C-terminal halves where all contain a conserved KXXXGXXPWE motif, suggesting that they might recognize the same receptor as LsbB. This notion was supported by the fact that truncated peptides with sequences derived from the C-terminal regions of two LsbB-related bacteriocins inhibited the activity of LsbB, in the same manner as found with the truncated version of LsbB. Taken together, these structure-function studies provide strong evidence that the receptor-binding parts of LsbB and sequence-related bacteriocins are located in their C-terminal halves.

AB  - The aim of this study was to identify and characterize the lactic acid bacteria (LAB) of artisanal Golija raw and cooked cows' milk cheeses traditionally manufactured without the addition of starter culture. A total of 188 Gram-positive and catalase-negative isolates of Golija cheeses were obtained from seven samples of different ripening time. Phenotype-based assays as well as rep-PCR and 16S rDNA sequence analysis were undertaken for all 188 LAB strains. The most diverse species were isolated from 20-day-old BGGO8 cheese (Lactobacillus fermentum, Lactobacillus plantarum, Lactobacillus casei/paracasei, Lactobacillus sucicola, Lactococcus lactis subsp. lactis, Lactococcus lactis subsp. lactis by. diacetylactis, Enterococcus faecium, Enterococcus durans and Leuconostoc mesenteroides). In other Golija cheeses Lactobacillus reuteri, Lactobacillus curvatus, Lactobacillus rhamnosus, Lactococcus lactis subsp. cremoris, Lactococcus garvieae, Streptococcus thermophilus and Leuconostoc pseudomesenteroides were found. Pronounced antimicrobial properties showed enterococci (13/42) and lactococci (12/31), while the good proteolytic activity demonstrated lactococci (13/31) and lactobacilli (10/29).

AB  - The aim of this study was to investigate the composition of lactic acid bacteria (LAB) in autochthonous young cheeses, sweet creams and sweet kajmaks produced in the Vlasic mountain region of central Bosnia and Herzegovina near the town of Travnik over a four season period. These three products were made from cow's milk by a traditional method without the addition of a starter culture. Preliminary characterization with phenotype-based assays and identification using rep-PCR with a (GTG)(5) primer and 16S rDNA sequence analysis were undertaken for 460 LAB isolates obtained from all the examined samples. Fifteen species were identified as follows: Lactococcus lactis, Lactococcus raffinolactis, Lactococcus garviae, Lactobacillus casei, Lactobacillus plantarum, Lactobacillus helveticus, Enterococcus faecium, Enterococcus durans, Enterococcus faecalis, Enterococcus italicus, Leuconostoc mesenteroides, Leuconostoc pseudomesenteroides, Leuconostoc lactis, Streptococcus thermophilus and Streptococcus mitis. A wide genotypic and phenotypic heterogeneity of the species was observed, particularly within the Lc. lactis strains. In all of the tested dairy products across four seasons, a significantly positive correlation (r = 0.690) between the presence of lactococci and enterococci and a negative correlation (r = 0.722) between the presence of lactococci and leuconostocs were recorded. Forty-five percent of the lactobacilli and 54.4% of the lactococci exhibited proteolytic activity, whereas 18.7% of the total LAB isolates exhibited antimicrobial activity.

AB  - Functional characterization of the multidrug resistance CmbT transporter was performed in Lactococcus lactis. The cmbT gene is predicted to encode an efflux protein homologous to the multidrug resistance major facilitator superfamily. The cmbT gene (1377 bp) was cloned and overexpressed in L. lactis NZ9000. Results from cell growth studies revealed that the CmbT protein has an effect on host cell resistance to lincomycin, cholate, sulbactam, ethidium bromide, Hoechst 33342, sulfadiazine, streptomycin, rifampicin, puromycin and sulfametoxazole. Moreover, in vivo transport assays showed that overexpressed CmbT-mediated extrusion of ethidium bromide and Hoechst 33342 was higher than in the control L. lactis NZ9000 strain. CmbT-mediated extrusion of Hoechst 33342 was inhibited by the ionophores nigericin and valinomycin known to dissipate proton motive force. This indicates that CmbT-mediated extrusion is based on a drug-proton antiport mechanism. Taking together results obtained in this study, it can be concluded that CmbT is a novel major facilitator multidrug resistance transporter candidate in L. lactis, with a possible signaling role in sulfur metabolism.

AB  - The genetic context of the bla(NDM-1) gene in the genome of Pseudomonas aeruginosa MMA83 was investigated. Sequencing of the cosmid selected for the bla(NDM-1) gene revealed the presence of two bla(NDM-1) copies in the genome of P. aeruginosa MMA83 in a unique genetic environment. Additionally, mating assays, DNA-DNA hybridization, and an S1 nuclease assay strongly suggest that the blaNDM-1 gene in P. aeruginosa MMA83 is chromosome borne.

AB  - The present study was carried out to test the colonic mucosal response of rats to oral supplementation with Lactobacillus fermentum BGHI14 and to correlate the tissue reaction to trinitrobenzenesulfonate (TNBS)-induced colitis with mucosal barrier alterations caused by bacterial ingestion. An immune cell-mediated reaction of healthy colonic tissue was noticed after bacterial feeding. After prolonged bacterial treatment, the observed reaction had retreated to normality, but the mRNA levels of proinflammatory cytokines interleukin-1 beta (IL-1 beta) and tumor necrosis factor alpha (TNF-alpha) remained elevated. These data point to the chronic low-grade inflammation that could be caused by long-term probiotic consumption. Although no detrimental effects of bacterial pretreatment were noticed in colitic rats, at least in the acute state of disease, the results obtained in our study point to the necessity of reassessment of existing data on the safety of probiotic preparations. Additionally, probiotic effects in experimental colitis models might depend on time coordination of disease induction with treatment duration.

AB  - Lactobacillus helveticus BGRA43 is a human intestinal isolate showing antimicrobial activity, amongst others, against Yersinia enterocolitica, Shigella sonnei, Shigella flexneri, and Streptococcus pneumoniae. BGRA43 produces PrtH proteinase with proteolytic activity on both casein and beta-lactoglobulin (BLG). BGRA43 is able to reduce the allergenicity of BLG. Bioactive peptides released in BGRA43 fermented milk are potent modulators of innate immunity by modulating the production of proinflammatory cytokines IL-6 and TNF-alpha. BGRA43 is able to survive in simulated gastric and intestinal conditions. The growth of BGRA43 in milk results in a fast acidification lowering the milk pH to 4.53 generating mild, homogeneous, and viscous yogurt-like product. The strain BGRA43 grows suitably in pure cow or goat's milk as well as in milk containing inulin or nutrim even when they are used as the sole carbon source. It is suggested that strain BGRA43 could be used as a single-strain culture for the preparation of yogurt-like products from bovine or caprine milk. Overall, L. helveticus BGRA43 could be considered as a potential probiotic candidate with appropriate technological properties attractive for the dairy industry.

AB  - Lactobacillus helveticus BGRA43 isolated from human intestines shows antimicrobial activity against foodborne pathogens and during fermentation in milk releases peptides with demonstrated anti-inflammatory properties. In this study, it was found that strain BGRA43 exhibits antimicrobial activity against human pathogens Yersinia enterocolitica, Shigella sonnei, S. flexneri and Streptococcus pneumoniae. Strain BGRA43 was able to survive in simulated gastric juice containing milk and retained cell number stability during the incubation in simulated intestinal conditions. In addition, LC/MS/MS analysis showed the ability of BGRA43 to hydrolyze beta-lactoglobulin. Abundant growth of strain BGRA43 occurred in the presence of prebiotics inulin or concentrated oat bran beta-glucan (Nutrim (R)), even when used as the sole carbon. source. Similarly, strain BGRA43 grew satisfactorily in pure cow's or goat's milk as well as in the milk containing inulin or Nutrim (R). Using the probiotic strain BGRA43 as a single starter strain, fermented milk products obtained from cow's or goat's milk with or without inulin or Nutrim (R) contained about 10(7) CFU/mL. The products were homogeneous and viscous and the best sensory scores were observed for fermented milk beverage made from reconstituted skimmed milk, whole cow's milk and whole goat's milk supplemented with 1 % inulin.

AB  - Soj Enterococcus faecalis BGPT1-10P je izolovan iz domaćeg polutvrdog sira, poreklom sa Stare Planine. Rezultati pokazuju da soj BGPT1-10P sintetiše termolabilan bakteriocin, enterolizin A, sa širokim spektrom delovanja, uključujući patogene bakterije roda Listeria i Candida. EntL gen, odgovoran za sintezu ovog bakteriocina, je hromozomalno lokalizovan. Analiza nukleotidne sekvence entL gena kod prirodnog izolata En. faecalis BGPT1-10P je identična sa entL genom soja En. faecalis LMG 2333, koji je prethodno okarakterisan. Pokazana je jedinstvena sekvenca entL gena i njegove okoline, koju čine orf1, orf2 i orf3 geni, kao i scpE gen. Prvi put je kod prirodnog izolata okarakterisan scpE gen, koji kodira virulentni faktor stafopain peptidazu. Funkcionalna analiza entL gena je pokazala da je kompletna genetička informacija, neophodna za sintezu i aktivnost enterolizina A, sadržana u entL genu. Soj BGPT1-10P osim enterolizina, sintetiše i želatinazu i citolizin i sadrži set različitih virulentnih faktora. Pored toga, BGPT1-10P nosi ermB i tetM gene, odgovorne za rezistenciju na eritromicin i tetraciklin.
AB  - Strain Enterococcus faecalis BGPT1-10P was isolated from artisanal semi-hard homemade cheese from Stara Planina, Serbia. Results showed that BGPT1-10P synthesized a heat labile bacteriocin with a broad spectrum of activity, including Listeria and Candida species. Further analysis revealed that synthesized bacteriocin is enterolysin A. Moreover, the entL gene encoding enterolysin A was found to be located on the chromosome. The entL gene was cloned and sequenced. Analysis of nucleotide sequence showed that the entL gene in natural isolate En. faecalis BGPT1-10P is identical to that of the entL gene described previously in En. faecalis LMG 2333. Within the cloned DNA fragment containing the entL gene, four ORFs were detected. One of them was identified as the scpE gene, which encodes a virulent factor staphopain peptidase. Functional analysis of the entL gene showed that the complete genetic information necessary for the synthesis of enterolysin A were directly linked solely to it. Strain BGPT1-10P also synthesized gelatinase and citolysin, and contained a set of virulent factors. In addition, BGPT1-10P carries the ermB and tetM genes conferring the resistance to erythromycin and tetracycline, respectively.

AB  - Staphylococcus epidermidis strains were isolated from the expressed human breast milk (EHM) of 14 healthy donor mothers. Genetic diversity was evaluated using RAPD-PCR REP-PCR and pulse-field gel electrophoresis (PFGE). PFGE allowed the best discrimination of the isolates, since it provided for the greatest diversity of the analyzed genomes. Among the S. epidermidis strains, resistance to gentamicin, tetracycline, erythromycin, clindamycin or vancomycin was detected, whilst four isolates were multiresistant. The results from our study demonstrate that staphylococci from EHM could be reservoirs of resistance genes, since we showed that tetK could be transferred from EHM staphylococci to Gram-negative Escherichia coli. Most of the staphylococcal strains displayed excellent proteolytic and lipolytic activities. Additionally, the presence of ica genes, which was related to their ability to form a biofilm on tissue culture plates, and the presence of virulence factors including autolysin/adhesin AtLE, point to their pathogenic potential.

AB  - Lactococcus lactis subsp. lactis BGMN1-5 produces a leaderless class II bacteriocin called LsbB. To identify the receptor for LsbB, a cosmid library of the LsbB-sensitive strain BGMN1-596 was constructed. About 150 cosmid clones were individually isolated and transferred to LsbB-resistant mutants of BGMN1-596. Cosmid pAZILcos/MN2, carrying a 40-kb insert, was found to restore LsbB sensitivity in LsbB-resistant mutants. Further subcloning revealed that a 1.9-kb fragment, containing only one open reading frame, was sufficient to restore sensitivity. The fragment contains the gene yvjB coding for a Zn-dependent membrane-bound metallopeptidase, suggesting that this gene may serve as the receptor for LsbB. Further support for this notion derives from several independent experiments: (i) whole-genome sequencing confirmed that all LsbB-resistant mutants contain mutations in yvjB; (ii) disruption of yvjB by direct gene knockout rendered sensitive strains BGMN1-596 and IL1403 resistant to LsbB; and (iii) most compellingly, heterologous expression of yvjB in naturally resistant strains of other species, such as Lactobacillus paracasei and Enterococcus faecalis, also rendered them sensitive to the bacteriocin. To our knowledge, this is the first time a membrane-bound peptidase gene has been shown to be involved in bacteriocin sensitivity in target cells. We also demonstrated a novel successful approach for identifying bacteriocin receptors.

Strain L. paracasei BGNK1-62 contained the bacSJ2-8/bacSJ2-8i gene cluster, but did not produce bacteriocin BacSJ possibly due to absence of the abcT and acc genes. Hence, these genes were introduced into BGNK1-62 by transformation with constructed plasmid pA2A, after which BacSJ was produced.

AB  - Adhesion of bacteria to mucosal surfaces and epithelial cells is one of the key features for the selection of probiotics. In this study, we assessed the adhesion property of Lactococcus lactis subsp. lactis BGKP1 based on its strong autoaggregation phenotype and the presence of the mucin binding protein (MbpL). Genes involved in aggregation (aggL) and possible interaction with mucin (mbpL), present on the same plasmid pKP1, were previously separately cloned in the plasmid pAZIL. In vivo and in vitro experiments revealed potentially different physiological roles of these two proteins in the process of adherence to the intestine during the passage of the strain through the gastrointestinal tract. We correlated the in vitro and in vivo aggregation of the BGKP1-20 carrying plasmid with aggL to binding to the colonic mucus through nonspecific hydrophobic interactions. The expression of AggL on the bacterial cell surface significantly increased the hydrophobicity of the strain. On the other hand, the presence of AggL in the strain reduced its ability to adhere to the ileum. Moreover, MbpL protein showed an affinity to bind gastric type mucin proteins such as MUC5AC. This protein did not contribute to the binding of the strain to the ileal or colonic part of the intestine. Different potential functions of lactococcal AggL and MbpL proteins in the process of adhesion to the gastrointestinal tract are proposed.

AB  - Traditional fermented foods are the best source for the isolation of strains with specific traits to act as functional starters and to keep the biodiversity of the culture collections. Besides, these strains could be used in the formulation of foods claimed to promote health benefits, i.e. those containing probiotic microorganisms. For the rational selection of strains acting as probiotics, several in vitro tests have been proposed. In the current study, we have characterized the probiotic potential of the strain Lactobacillus paraplanta rum BGCG11, isolated from a Serbian soft, white, homemade cheese, which is able to produce a "ropy" exopolysaccharide (EPS). Three novobiocin derivative strains, which have lost the ropy phenotype, were characterized as well in order to determine the putative role of the EPS in the probiotic potential. Under chemically gastrointestinal conditions, all strains were able to survive around 1-2% (10(6)-10(7) cfu/ml cultivable bacteria) only when they were included in a food matrix (1% skimmed milk). The strains were more resistant to acid conditions than to bile salts and gastric or pancreatic enzymes, which could be due to a pre-adaptation of the parental strain to acidic conditions in the cheese habitat. The ropy EPS did not improve the survival of the producing strain. On the contrary, the presence of an EPS layer surrounding the strain BGCG11 hindered its adhesion to the three epithelial intestinal cell lines tested, since the adhesion of the three non-ropy derivatives was higher than the parental one and also than that of the reference strain Lactobacillus rhamnosus CC. Aiming to propose a potential target application of these strains as probiotics, the cytokine production of peripheral blood mononuclear cells (PBMC) was analyzed. The EPS-producing L paraplantarum BGCG11 strain showed an anti-inflammatory or immunosuppressor profile whereas the non-ropy derivative strains induced higher pro-inflammatory response. In addition, when PBMC were stimulated with increasing concentrations of the purified ropy EPS (1, 10 and 100 mu g/ml) the cytokine profile was similar to that obtained with the EPS-producing lactobacilli, therefore pointing to a putative role of this biopolymer in its immune response.

AB  - Screening of 203 Bacillus sp. natural isolates for antimicrobial activity against phytopathogenic bacteria showed that 127 tested strains inhibit at least one sensitive strain, which illustrates their potential use as biocontrol agents. Among them, 104 isolates showed significant antagonism against Xanthomonas oryzae pv. oryzae, and only one of these (VPS50.2) synthesizes bacteriocin. An additional screening tested whether 51 isolates contained genes involved in the biosynthesis of lipopeptides of the iturin and surfactin classes. Results show that 33 isolates harbour the operon for iturin biosynthesis, and six of them carry the sfp gene, responsible for the biosynthesis of surfactin. Lipopeptide purification from the supernatant of isolate SS12.9 (identified as B. subtilis or B. amyloliquefaciens) was performed using ethyl acetate extraction, ultrafiltration and reversed phase HPLC. Mass spectrometry analysis confirmed that isolate SS12.9 produces a substance of the iturin class with potential for biocontrol of X. oryzae pv. oryzae.

AB  - Pseudomonas sp. strain ATCC19151 is a natural isolate from sewage with the ability to degrade detergents. Genes encoding potential choline sulfatase (betC), substrate-binding ABC transporter protein (betD), sulfate transporter (betE), and divergent putative transcriptional regulator (betR) were cloned and characterized from strain ATCC19151. In silico analysis revealed that (1) the BetC protein belongs to alkPPc superfamily and shares CXPXR sequence with the cysteine sulfatases of group I, (2) BetR belongs to the LysR family of transcriptional regulators, (3) BetD is part of the PBPb superfamily of periplasmic and membrane-associated proteins, and (4) BetE is a permease and contains STAS domain. Insertional mutagenesis and genetic complementation show that betC gene encodes a functional choline sulfatase. Analysis of the betC (P (betC) ) and betR (P (betR) ) promoters revealed that they are inducible. BetR activates betC and betR transcription in the presence of choline sulfate, whilst in the absence of choline sulfate, BetR represses its own transcription. It was further established that BetR directly binds to betC-betR intergenic region in vitro, with higher affinity in the presence of choline sulfate as cofactor. Transcription of betC and betR was not induced in the presence of high concentration of NaCl.

AB  - This work reports, for the first time, the presence of New Delhi metallo-beta-lactamase 1 (NDM-1) in Pseudomonas aeruginosa. Moreover, this is the first report of the NDM-1 presence in the Balkan region. Cosmid gene libraries of carbapenem-nonsusceptible Pseudomonas aeruginosa clinical isolates MMA83 and MMA533 were screened for the presence of metallo-beta-lactamases. Accordingly, both MMA83 and MMA533 carried the bla(NDM-1) gene. Pulsed-field gel electrophoresis (PFGE) analysis indicated that strains MMA83 and MMA533 belonged to different clonal groups. Five additional isolates from different patients clonally related to either MMA83 or MMA533 were found to be NDM-1 positive.

AB  - Molecular detection and surveillance of theresistance genes harboured byPseudomonas aeruginosa are becomingincreasingly important in assessing andcontrolling spread and colonization inhospitals, and in guiding the antibiotictreatment of infections. Metallo-blactamase (MBL)-producing P. aeruginosastrains are slowly but steadily increasingwithin hospitals, causing outbreaks and/orhyperendemic situations in some centres,mostly in the Far East and the south ofEurope (Queenan & Bush, 2007). Theglobal dissemination of MBL-producingP. aeruginosa strains has also reached theBalkan region (Lepsanovic et al., 2008;Sardelic et al., 2003). The objective of ourstudy was to detect and characterize P.aeruginosa isolates producing MBLs fromthe 400-bed paediatric tertiary carehospital Mother and Child Health Instituteof Serbia ‘Dr Vukan Cupic’

Metallo-blactamase (MBL)-producing P. aeruginosastrains are slowly but steadily increasingwithin hospitals, causing outbreaks and/orhyperendemic situations in some centres,mostly in the Far East and the south ofEurope (Queenan & Bush, 2007). Theglobal dissemination of MBL-producingP. aeruginosa strains has also reached theBalkan region (Lepsanovic et al., 2008;Sardelic et al., 2003). The objective of ourstudy was to detect and characterize P.aeruginosa isolates producing MBLs fromthe 400-bed paediatric tertiary carehospital Mother and Child Health Instituteof Serbia ‘Dr Vukan Cupic’",

AB  - Background: Aggregation may play a main role in the adhesion of bacteria to the gastrointestinal epithelium and their colonization ability, as well as in probiotic effects through co-aggregation with intestinal pathogens and their subsequent removal. The aggregation phenomenon in lactococci is directly associated with the sex factor and lactose plasmid co-integration event or duplication of the cell wall spanning (CWS) domain of PrtP proteinase. Results: Lactococcus lactis subsp. lactis BGKP1 was isolated from artisanal semi-hard homemade cheese and selected due to its strong auto-aggregation phenotype. Subsequently, non-aggregating derivative (Agg(-)) of BGKP1, designated as BGKP1-20, was isolated, too. Comparative analysis of cell surface proteins of BGKP1 and derivative BGKP1-20 revealed a protein of approximately 200 kDa only in the parental strain BGKP1. The gene involved in aggregation (aggL) was mapped on plasmid pKP1 (16.2 kb), cloned and expressed in homologous and heterologous lactococci and enterococci. This novel lactococcal aggregation protein was shown to be sufficient for cell aggregation in all tested hosts. In addition to the aggL gene, six more ORFs involved in replication (repB and repX), restriction and modification (hsdS), transposition (tnp) and possible interaction with mucin (mbpL) were also located on plasmid pKP1. Conclusion: AggL is a new protein belonging to the collagen-binding superfamily of proteins and is sufficient for cell aggregation in lactococci.

AB  - Aims: The presented study was aimed to reveal transcriptional regulation of genes involved in SDS degradation (sdsA and sdsB) in Pseudomonas sp. ATCC19151. In addition, the ability of Pseudomonas sp. ATCC19151 to degrade anionic surfactants present in commercial detergent and septic tank drain was analysed. Methods and Results: Strain ATCC19151, at 30 degrees C, degrades all SDS present in the liquid medium (up to 4% w/v of SDS) within 48 h. ATCC19151 grows in the presence up to 15% (v/v) 'Fairy' commercial detergent and mineralizes 35% of present anionic surfactants. Analysis of the sdsA (P(sdsA)) and divergent sdsB (P(sdsB)) gene promoter activities revealed that SdsB acts as a positive regulator of sdsA and sdsB transcription. P(sdsA) and P(sdsB) activities rose significantly in the presence of the SDS, indicating inducibility of sdsA and sdsB transcription. DNA-binding assay indicated that SdsB directly regulates the transcription of sdsA and sdsB genes. Strain ATCC19151 grew in a sterile septic tank drain and on commercial detergent as sole source of carbon. Conclusions: SdsA enables Pseudomonas sp. ATCC19151 to utilize SDS as a sole carbon source. SdsB is positive transcriptional regulator of sdsA and sdsB genes. Significance and Impact of the Study: Ability of ATCC19151 to degrade anionic surfactants makes Pseudomonas sp. ATCC19151 a good candidate for bioremediation.

AB  - Aims: The study of proteolytic activity and examination of proteinase gene region organization in proteolytically active Lactobacillus plantarum strains from different natural sources. Methods and Results: A set of 37 lactobacilli was distinguished by using multiplex PCR assay. Results showed that 34 strains were Lact. plantarum and three of them were Lact. paraplantarum. The examination of proteolytic activity revealed that 28 Lact. plantarum and two Lact. paraplantarum hydrolyse beta-casein. Further analyses of all proteolytically active Lact. plantarum with primers specific for different types of CEPs demonstrated that strain BGSJ3-18 has prtP catalytic domain as well as prtP-prtM intergenic region showing more than 95% sequence identity with the same regions present in Lact. paracasei, Lact. casei and L. lactis. No presence of prtB, prtH or prtR proteinase genes was detected in any of tested Lact. plantarum strains. Conclusions: One out of 28 analysed Lact. plantarum strains harbours the prtP-like gene. The other proteolytically active Lact. plantarum probably possesses a different type of extracellular proteinase(s). Significance and Impact of the Study: It is the first report about the presence of the prtP-like gene in Lact. plantarum, which illustrates the mobility of this gene and its presence in different species.
