【中文摘要】 采用液体深层培养方法 ,研究了杏鲍菇对碳、氮营养的利用情况。结果表明 ,杏鲍菇Pe970 1菌株菌丝生长的最适碳源为果糖 ,其次为麦芽糖 ,而对甘露醇的利用最差 ;有机氮比无机氮更适于杏鲍菇菌丝生长 ,最适有机氮为蛋白胨 ,最适无机氮为硝酸铵 ,硫酸铵次之 ,碳酸铵几乎不能被利用。此外 ,各处理培养液的 pH均呈上升趋势 ,发酵终止 pH在 7.0左右。
【英文摘要】 The utilization of Pleurotus eryngii with different C sources and N sources was studied under submerged culture conditions in this experiment. The results showed that fructose was the best C source for the hyphal growth of strain Pe9701 of Pleurotus eryngii, maltose took the second place, while mannitol was the worst; and for the N sources, the organic nitrogen was better than the inorganic nitrogen, peptone was the best organic nitrogen, ammonium nitrate was the best inorganic nitrogen, while anmmonium sulfate took the second place and ammonium carbonate could almost not be utilized. In addition,the experiment proved that the pH of various kinds of liquid media presented an upward trend, and the pH at the end of the fermentation was about 7.0.
