In this study, we collected 6 traditional dairy samples from Kazak herdsman families in Xinyuan County. Total 22 strains were isolated and identified. The strains belong to 5 genera, including Lactobacillus, Enterococcus, Leuconostoc, Acetobacter, and Bacillus. Among them, L. plantarum A1-3-15 exhibits good bile salt and acid tolerance. This study indicated that the traditional Kazak dairy product exhibits good biodiversity and is a good resource of probiotics. The health function of the strains isolated is worth to be further studied.
