Biodiversity of lactic acid bacteria isolated from human breast milk of Kashi area in Xinjiang

Abstract:

[Objective] Assessment the diversity of lactic acid bacteria in the breast milk of healthy women. [Methods] The diversity of lactic acid bacteria was analyzed by using pure culture, repetitive genomic fingerprinting (Rep-PCR) analysis patterns and 16S rRNA gene sequence analysis. [Results] A total of 193 strains of lactic acid bacteria were obtained from eleven breast milk samples. The phylogenetic analysis showed that these strains belonged to four phylogenetic groups, they were Lactobacillus, Streptococcus, Lactococcus and Enterococcus respectively. The dominant genus was Enterococcus, which is up to 46%. [Conclusion] The abundant diversity of lactic acid bacteria in the human breast milk of Kashi area in Xinjiang provided rich resources for exploiting probiotic lactic acid bacteria products.
