Abstract :

Viability and survive of Lactobacillus strains under acidic environment are the most important criteria for selection as probiotic. Seven Lactobacillus strains isolated from cowâ��s colostrum were tested for viability and resistance to acidity. This viability of Lactobacillus were examined at 0, 7, 14 and 21 days when the counts were variable, ranging between 5-6.5 log cfu/ml. Specific growth rate (�¼) and generation time of Lactobacillus strains were determined. Acid tolerance was determined by introducing the strains of Lactobacillus in skimmed milk at pH=4.3 and enumerating during storage at 4�°C. All strains showed ability to resist under SGF and bile salt but L. rhamnosus MB5516 are more resistance and showed superior survival abilities and resistance to acidity than others strains. Our result suggests that strains resistant to acidity seem to be suitable for food and biotechnological industry.
