| Abstract: | This paper focused on the isolation methods of lactic acid bacteria from the filtrate and lotion of Kefir. The resultshowed: when the improved whey media added with 0.5% sorbate by dish pour; the anaerobic culture could achieve much bettereffect on the isolation of lactic acid bacteria. Moreover, the strains in the filtrate were growing better than those in the lotion. |
