植物乳酸菌高密度发酵培养基优化
Contemporary Chemical Industry(2020)
Abstract
主要探索了如何提高植物乳杆菌高密度发酵活菌数,研究了培养基成分、pH值等发酵条件.结果表明:植物乳酸菌生长最适碳源是淀粉、葡萄糖,最适氮源是酵母浸粉;二价锰离子和无机盐对菌体的生长有促进作用;最适培养基组成:酵母浸粉3%,醋酸钠0.5%,柠檬酸三铵0.2%,磷酸氢二钾0.3%,氯化钠0.2%,吐温800.1%,硫酸锰0.3‰,硫酸镁0.2‰,无水葡萄糖2.2%,碳酸钙0.5%,淀粉4.4%.在5 L半自动发酵罐中,发酵16 h左右,活菌数为8.9×1011 CFU/mL,发酵液保存周期较长,在75 d跟踪检测中活菌数无数量级变化.
