摘要: 采用摇瓶培养法对2种真姬菇的发酵工艺进行研究,结果表明:真姬菇Ⅰ、Ⅱ发酵生产菌丝体及胞外多糖的碳源是葡萄糖,氮源是酵母膏;液体发酵培养基是葡萄糖3%、酵母膏 0.4%、vitB1 10mg/100ml、KH2PO4 0.1%、MgSO4 0.1%,pH值为6.0;液体发酵的优化条件是初始pH 6.0~7.0,振荡速度110~130r/min,培养温度25~28℃,装液量150ml/250ml。2种真姬菇菌丝体及胞外多糖产量较高,真姬菇Ⅰ菌丝体干重、胞外多糖产量分别是 3.92、8.83 mg /ml;真姬菇ⅠⅠ菌丝体干重、胞外多糖产量分别是3.25、7.69 mg /ml,即真姬菇Ⅰ摇瓶发酵菌丝体干重、胞外多糖产量高于真姬菇Ⅱ。

Abstract: According to the research of the fermentation technique of two speice of Hypsizigus marmoreus by rotation culture .The result is: glucose is the carbon source of mycelium and extra cellular polysaccharide of Hypsizigus marmoreusⅠ and Hypsizigus marmoreusⅡ in fermentation, yeast extractea is the nitrogen source; liquid fermentation medium consist of 3% glucose, 0.4% yeast extractea, vitB1 10mg/100ml、KH2PO4 0.1%、MgSO4 0.1%,and PH value is 6.0; optimum condition for liquid fermentation includes: pH 6.0~7.0,bed rotation speed 110~130r/min,temperature 25~28℃, volum 150ml/250ml at the beginning. mycelium and extra cellular polysaccharide of two speice of Hypsizigus marmoreus have high production and they are: 3.92mg/ml for the dry weight of mycelium and 8.83 mg /ml for extra cellular polysaccharide of Hypsizigus marmoreusⅠ; while 3.25mg/ml for the dry weight of mycelium and 7.69 mg /ml for extra cellular polysaccharide of Hypsizigus marmoreus Ⅱ, The production of the dry weight of my mycelium and extra cellular polysaccharide of Hypsizigus marmoreus Ⅰin rotation fermentation is more than Hypsizigus marmoreusⅡ,s.
