摘　　要：研究了不同碳源、氮源、碳氮比、无机盐及其浓度对白灵侧耳菌丝生长的影响。结果表明,白灵侧耳菌丝生长的最适碳源是葡萄糖;最适氮源是蛋白胨;最适碳氮比为20∶1;促进菌丝生长的最适KH2PO4、MgSO4浓度分别为0.3%、0.1%;最适NaCl、KCl、CaSO4.2H2O浓度均为0.5%;CaSO4.2H2O对菌丝生长的促进作用最大;H3BO3对菌丝生长的影响最小;ZnSO4.7H2O对白灵侧耳菌丝生长有明显的抑制作用。Effects of different carbon and nitrogen sources, C/N ratio, inorganic salts on the mycelium growth of Pleurotus nebrodensis were studied. The results showed that the optimum carbon source, nitrogen source were glucose and peptone. The optimum ratio of C/N was 20： 1. The optimum concentrations of KH2PO4, MgSO4, NaCl, KCl, CaSO4·2H2O were 0.3% ,0.1% ,0.5% ,0.5% and 0.5% respectively. Among the inorganic salts tested, CaSO4·2H2O was the best on the mycelium growth; and the H3BO3 was the least. ZnSO4·7H2O obviously inhibited the mycelium growth of P. nebrodensis .
