植物乳杆菌增菌培养基碳源优化

Optimization of carbon of culture medium for accumulating Lactobacillus plantarum

对植物乳杆菌高效培养基碳源进行优化,选择廉价碳源。先确定植物乳杆菌的最适培养温度、最适pH、最适接种量。比较不同碳源的替代效果,选择发酵性能最好的碳源,优化碳源比例。结果在不降低发酵性能的前提下,蔗糖能部分替代葡萄糖作为碳源,节约了成本。

Objective：To optimize of culture medium of Laetobacillus plantarum, select low-cost carbon. Methods：confirm the optimum temperature of plant lactobacillus, the optimum pH, the optimal quantity comparing the substitution effect of different carbon source, choose the best carbon source, the fermentation performance optimization of carbon source, result：without reducing fermentation performance under the premise of sucrose can partly replace glucose as carbon source, saving the cost.
