降胆固醇干酪乳杆菌WB生长培养基的筛选

Choice of the optimal medium for the growth of cholesterol-reducing Lactobacillus casei WB

降胆固醇干酪乳杆菌WB在不同种类选择性培养基上生长培养后,比较活菌菌落数、菌落及溶钙圈大小。结果显示:MRS培养基最适合降胆固醇乳酸菌WB的培养,活菌数最多、菌落及溶钙圈最大。厌氧培养后效果更佳。

The optimal media for the growth of cholesterol-reducing Lactobacillus casei WB was chosen by detecting the number, size of colony and the size of calcium-dissolving zone when the bacteria grew in different media. The results showed that the growth of the cholesterol-reducing lactobacillus was best, the number of living bacteria was the largest and the calcium-dissolving zone was the biggest when the bacteria grew in the MRS media, which is better after anaerobic treatment.
