Descrição: Lactic acid bacteria MA2 from Tibet kefir grain was identified as Lactobacillus plantarum by morphology, physiological and biochemistry methods and 16S rDNA sequencing. The results of tolerance of acid and bile salt show that MA2 strain has strong acid tolerance and bile salt tolerance at pH 2.0 and 0.3% oxgall concentration. The results of animal test indicate that MA2 can increase the amount of lactic acid bacteria and bifidobacteria in feces of rats, and improve the balance of intestinal flora. MA2 is a kind of potential probiotic with practical application.
