Abstract:

In order to identify genus and species of two stains of lactic acid bacteria with antibacterial functions, BY-3-2 and SQ-3-2 were separated from Koumiss. Their physiological and biochemical characteristics and 16S rDNA sequence were analyzed. Results indicated that physiological and biochemical characteristics of BY-3-2 and SQ-3-2 were the same as those of Enterococcus. Moreover, strain BY-3-2 had the characteristics of E. faecium, and SQ-3-2 had the characteristics of E. durans, which was also supported by 16S rDNA sequence analysis.

Key words: lactic acid bacteria , isolation and identification , 16S rDNA sequence analysis
