植物乳杆菌增菌培养基碳源优化

摘要

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 Lactobacillus 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.
