The separation and Identification of lactobacillus to secrete Like-Coccidia bacteriocin in Kefir grains
摘要
Abstract
To screen lactic acid bacteria of bacteriostasis using MRS selection culture medium.The agar diffusion method with Oxford cup methord was adopted,combining physical and chemical resistance of the characteristics identification,antibacterial spectrum determination colony morphology and characteristics,physiological and biochemical experiment,and the berger's manual identification were exercised.The physiological and biochemical reaction was lactic acid.The bacteria colony morphology and characteristics were Coccidia and have inhibition for most of the gram negative bacteria,this strain was lactic acid milk aureus the diacetyl lactic acid subspecies.Identification and separation results was in the bacteriocins coccoid lactic acid bacteria,and the bacteriocin was the like-protein peptide.关键词
