产胆盐水解酶乳酸菌的分离、鉴定及降解胆固醇机理的初步研究
Isolation and Identification of Lactic Acid Bacteria Producing Bile Salt Hydrolase and Study on Mechnism of Recucing Colestrol
【摘要】 本文从开菲尔粒中分离出15株能降低胆固醇的菌,通过生理生化反应以及其他指标对这15株菌株进行鉴定,其中7株为球菌,8株为杆菌。对这15株菌进行复筛,最终筛选出一株能产胆盐水解酶的菌株,用全自动生化鉴定仪对这株菌做进一步的鉴定,其鉴定结果为干酪乳杆菌。
【Abstract】 In this test, 15 strains were isolated from the filtrate of kefir grains which can reduce cholesterol level, identified by physiological and biochemistry reaction and other indexes, 7 were coccus sp., 8 were bacillus sp.. Only one of them can produce bile salt hydrolase, it was lactobillus casei identified by micro station full automaticity.
