摘要
将薏苡仁添加到茯苓发酵罐液体发酵培养基中组成药性培养基,薏苡仁可促进茯苓的生长。文章研究了以薏苡仁为基质的茯苓发酵罐补料液体发酵,确定了最佳的补料时间和补料量。在最佳补料液体发酵工艺下,茯苓菌丝体产量达15.09g/L,茯苓胞外多糖产量达7.52g/L。
Poria cocos was promoted by coicis semen in fermentor when coicis semen was added in fermentation medium to be medicinal fermentation medium. Additional medium liquid fermentations of Poria cocos by coicis semen medium in fermentor were studied in this paper, the optimum additional medium times and additional medium quantities were determined. In the optimum addi- tional medium liquid fermentation, the dry weight of mycelium and the exocellular polysaccharide of Poria cocos was 15.09 g/L and 7.52 g/L respectively.
