【摘要】 采用单因素试验和响应曲面试验优化灵芝药性固体发酵培养基。优化所得培养基组成为:以啤酒糟为基质,料水比1:1.4,黄芪12.52%,葡萄糖4.78%,KH2PO40.21%,MgSO4·7H2O0.25%,VB1微量。在此优化条件下,灵芪菌质多糖含量高达8.42mg/g,较优化前提高了29.54%。更多还原

【Abstract】 Single-factor and response surface test were used for optimization of Ganoderma lucidum medicinal solid fermentation medium.Optimized medium composition were as follows:brewer’s spent grain as substrate,the ratio of material to water was 1:1.4,Astragalus membranaceus 12.52%,glucose 4.78%,KH2PO40.21%,MgSO4·7H2O 0.25%,V B1 trace.Under the optimized conditions,GAPS concertration reached up 8.42mg/g,increased by 29.54% compared with unoptimization.更多还原
