Abstract: In this paper,752samples of fresh milk and dairy products were collected from519 households in different pastoral areas of Inner Mongolia, and the lactobacillus in the samples was isolated, with its biological properties studied. A total of 765 strains were identified, belonging to 28 species and subspecies of Lactobacellus,2 species of Bifidobacterium,9 species of Enterococcus,3species and subspecies ofLactococcus,1 species of Streptococcus,6 species and subspecies of Leuconostoc,and 1 species of Pediococcus, which indicated that in the milk and dairy products of Inner Mongolia, there widely spread many kinds of lactobacillus. Some strains had high adaptability to environmental temperature and pH, and even, some of them had stronger capability of using melezitose, melibiose and raffinose, etc as carbon source.
