AB  - Soj Lactococcus lactis subsp. lactis BGIS29 je prirodni izolat iz sira proizvedenog u domaćinstvu koji proizvodi bakteriocin IS29 i proteinazu PI-tipa. Rezultati dobijeni biohemijskom karakterizacijom bakteriocina IS29 sugerišu da on pripada klasi II bakteriocina. DNK-DNK hibridizacija i PFGE analiza su pokazali da su geni za proteinazu i proizvodnju bakteriocina locirani na različitim genetičkim elem- entima. Proizvodila proteinaze coja BGIS29 i bakteriocina IS29 zavise od koncentracije kazitona u medijumu za rast bakterija. Veće koncentracije kazitona imaju inhibitorni efekat na aktivnost proteinaze. Nasuprot tome, proizvodila bakteriocina IS29 je izraženija u medijumu koji sadrži veće koncentracije kazitona.
AB  - Strain Lactacoccus lactis subsp. lactis BGIS29, a natural isolate from homemade cheese produces the bacteriocin IS29 and the Pi-type proteinase. The results obtained by biochemical characterization of bacteriocin IS29 suggest that it belongs to class II of bacteriocins. The DNA-DNA hybridization and PFGE analysis showed that the genes for proteinase and bacteriocin production are located on separate genetic elements. Production of the proteinase of BGIS29 and the bacteriocin IS29 depend on the concentration of casitone in medium. Higher concentrations of casitone expressed an inhibitory effect on the proteinase activity. In contrast, production of bacteriocin IS29 was more pronounced in medium containing high casitone concentrations.

AB  - Autohtoni sojevi bakterija mlečne kiseline (BMK) su izolovane iz fermentisanih mlečnih proizvoda rađenih u domaćoj radinosti. Fermentisani mlečni proizvodi su sakupljani sa specifičnih ekoloških lokaliteta kao što su visoke planine (iznad 1200 m nadmorske visine), planinske visoravni, rečne doline, ostrva, obala Jadranskog mora, itd. Analiza kolekcije prirodnih izolata BMK je pokazala da izolati proizvode proteinaze, bakteriocine i egzopolisaharide. Pokazano je, takođe, da neki izolati laktokoka i laktobacila proizvode istovremeno dva različita bakteriocina. Pored toga određeni broj izolata proizvodi i proteinaze i bakteriocine. Nađeno je da prirodni izolati sintetišu specifične proteinaze. Analiza organizacije prt gena u prirodnim izolatima BMK je pokazala da četiri laktobacila poseduju organizaciju prt gena koja se razlikuje od do sada opisanih. Izučavanje regulacije gena koji kodiraju proteinaze, bakteriocine ili egzopolisaharide može olakšati konstrukciju specifičnih starter kultura za proizvodnju autohtonih fermentisanih mlečnih proizvoda, tj. fermentisanih proizvoda sa geografskim poreklom.
AB  - Autochthonous strains of lactic acid bacteria (LAB) were isolated from homemade fermented milk products. These products were collected from specific ecological localities such as high mountains (above 1200 m above sea level) mountain plateaus, river valleys, islands, Adriatic coast, etc. Analysis of LAB from the collection of natural isolates revealed that they produce proteinases, bacteriocins and exopolysaccharides. It was also shown that some isolates of lactococci and lactobacilli produce two bacteriocins simultaneously. According to their antimicrobial and biochemical properties most of the analyzed bacteriocins in natural isolates of lactococci were class 11 bacteriocins. In addition some isolates produced both proteinase and bacteriocin. Biosynthesis of specific proteinases was detected in natural isolates. Analysis of the prt gene organization among natural isolates of LAB showed that four isolates of lactobacilli exhibited prt genes organization different from those described so far. Elucidation of the regulation of the genes encoding proteinases, bacteriocins and exopolysaccharides could facilitate the construction of specific starter cultures for production of autochthonous fermented milk products, i.e. fermented products with a geographical origin.
