摘要
从酸奶中筛选得到高效降解胆固醇的乳酸菌株La-3,并对其胆固醇降解能力进行研究。通过单因素和正交实验,得到胆固醇降解最佳条件为培养时间72 h、胆固醇浓度1.5 mg/mL、接种量4%,胆固醇降解率达到51.2%。
A strain of efficient cholesterol - degrading lactobacillus La- 3 was screened from yoghourt, and its cholesterol -degrading ability was studied. The optimum condition for degradation of cholesterol were obtained by single factor and orthogonal test, that was, culture for 72 h, cholesterol concentration 1.5 mg/mL, inoculum size 4%, and the cholesterol - degradation rate was 51.2%.
