| Abstract: | In this study, medium composition and process conditions for the liquid-state incubation of Hypsizigus marmoreus in a shake flask were explored. The optimal medium composition was found to consist of 3 g/100 mL glucose, 1 g/100 mL corn starch, 1.5 g/100 mL soybean cake, 0.3 g/100 mL (NH4)2SO4, 0.2 g/100 mL KH2PO4, 0.1 g/100 mL MgSO4·7H2O and 10 mg/L Vitamin B1. Initial pH of 6.0, medium volume contained in a 500 mL flask of 140－150 mL, shaking speed of 180 r/min, incubation temperature of 26 ℃, incubation time of 72 h and inoculum size of 10%－12% were found optimal. |
