【摘要】 对肋脉羊肚菌进行液体摇瓶培养,以菌丝干重、胞内多糖产量及其得率为筛选指标,得到最适合肋脉羊肚菌生长的培养基条件为可溶性淀粉浓度2%、豆粕粉浓度1%、MgSO4·7H2O0.1%、KH2PO40.05%、初始pH7.5、培养温度28℃。培养8d后菌丝干重达16.94g/L,胞内多糖量达0.984g/L。更多还原

【Abstract】 The optimization of culture of Morchella costata (Vent.) Pers on liquid culture was studied. With dry weight of mycelium, inopolysaccharide(IPS) output and its yield. The results showed that the concentration of starch was 2%, the chorma of lobster sauce was 1%, the concentration of MgSO4·7H2O was 0.1% and the concentration of KH2PO4 was 0.05%, the initial pH of culture was 7.5, and the temperature was 28 ℃. The dry weight of mycelium reached 16.94 g/L, and the weight of inopolysaccharides(IPS) reached 0.984 g/L after culturing for 8 days.更多还原
