一株凝结芽孢杆菌的益生菌性能评价及产乳酸条件优化
Evaluation of probiotic performance and optimization of lactic acid production conditions of Bacillus coagulans
摘要
Abstract
In this study,the probiotic performance of Bacillus coagulans was evaluated,and the acid production conditions were optimized.The results showed that the survival rate of the strain could reach 40％at a temperature of 80 ℃,pH 2,and a bovine bile salt concentration of 0.3％,and it showed good tolerance to artificial gastric and intestinal juices.In the optimization of acid production conditions,it was found that the lactic acid yield could reach 16.36 g/L when fermented for 48 hours under the conditions of medium composition glucose 15 g/L,beef paste 15 g/L,peptone 15 g/L,dipotassium phosphate 6 g/L,culture temperature 40 ℃,initial pH 7.7,inoculum amount 0.5％,and shaker speed of 180 r/min.Therefore,this strain had good probiotic properties and lactic acid production ability and had a wide application prospect in the preparation and application of microecological preparations.关键词
