| Abstract: | 12 strains of Lactic acid bacteria were isolated from 5 traditional fermented yogurt samples of Russia’s Caucasus region.According to the morphological,physiological,biochemical characteristics,and the sugar-fermentation testing,among 12 strains,7 strain were identified as lactobacillus,which include 3 strains of Lactobacillus delbrueckii ssp.Bulgaricus,3 strains of Lactobacillus helveticus,and 1 strain of Lactobacillus reuteri;5 strains were identified as lactococcus,which include 3 strains of Streptococcus thermophilus and 2 strains of Lactococcus lactis spp.cremoris. |
