忍冬桑黄和蛹虫草两种药用真菌均可产活性多糖,共发酵模式是产生新化合物或提高化合物含量或药效的潜在方式。本研究尝试用忍冬桑黄和蛹虫草共发酵联产真菌多糖,并对其共发酵所得的菌丝体多糖开展抗氧化活性试验。结果表明,当忍冬桑黄和蛹虫草预先分别发酵3d和1d后再同时接种共发酵,两菌可以较好地进行共生长,菌体总量和总多糖得率显著高于两菌单独进行发酵时的相应量。进一步对适宜两菌共发酵的培养基进行了优化,获得适宜两菌共发酵高产多糖的培养基组成为:可溶性淀粉30g/L、牛肉粉12g/L、磷酸氢二钾和硫酸镁各1.5g/L。共发酵菌丝体中多糖和黄酮含量均高于两菌单个菌体中的相应含量,但三萜含量...

Both Sanghuangporus lonicericola and Cordyceps militaris can produce active polysaccharides. Co-fermentation mode is a potential way to produce new compounds or improve the content or bioactive efficacy of compounds. In this study, the co-fermentation of S. lonicericola and C. militaris was performed to produce polysaccharides, and the antioxidant activities of the mycelial polysaccharides were tested. The two fungal strains separately prefermented for 3 days and 1 day, and then in the same flask continuously fermentated. It was found that the ...
