Survival of Lactobacillus bifidus after freeze-drying
(Cryobiology, 1967)
Between 90 and 100% of Lactobacillus bifidus survived freeze-drying in media consisting of 8% sucrose, 1.5% gelatin, and 5% skim milk. The cultures in suspensions were 48 hrs old, and the approximate concentration of cells ...
Predicting the stability of freeze-dried Lacto-bacillus bifidus by the accelerated storage test
(Cryobiology, 1968)
In an accelerated storage test the logarithms of the number of surviving freeze-dried Lactobacillus bifidus declined linearly with time at three selected temperatures (36°, 45°, and 6°C). The logarithms of the calculated ...
