摘要: 本文分别对开菲尔滤液和洗液中乳酸菌的分离方法进行了研究。结果表明:使用添加了0.5%山梨酸钾的乳清改良培养基,倾注法(划线法)厌氧培养乳酸菌分离效果较好,并且滤液中的菌株比洗液中的长势更好,活力更高。

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.

Key words: Kefir grains, lactic acid bacteria, isolation
