摘    要:采用平板培养法研究了杏鲍菇菌丝的营养生理特性.结果表明:果糖、麦芽糖和葡萄糖等简单糖类是杏鲍菇菌丝生长的适宜碳源,最适碳源是果糖,对多糖、有机酸和甘露醇的利用较差;酵母粉、牛肉膏、玉米浆、蛋白胨和豆饼粉等有机氮源是杏鲍菇菌丝生长的适宜氮源,最适氮源为酵母粉,对尿素、铵盐和和硝酸盐利用较差,不能利用亚硝酸盐;在基础培养基中添加磷酸二氢钾和硫酸镁可以促进菌丝生长,但添加硫酸锌菌丝不能生长.

关 键 词:杏鲍菇  碳源  氮源  无机盐  生长速度  生长势

Abstract:The mycelium physiological property of Pleurotus eryngii(DC.ex Fr.) Quél was studied in this paper.The results showed that the suitable carbon sources for the mycelium growth of the P.eryngii were some monosaccharide(i.e.fructose,maltose and glucose),the optimism was fructose,and yet polysaccharides organic acids and mannitol grew slowly;the appreciate nitrogen sources were powdery yeast,beef extract,corn steep liquor,peptone and bean cake powder,the optimism was powdery yeast,but P.eryngii had a low ability of using urea,NH4Cl,and NaNO3,and NaNO2 can hardly be used.In the use of inorganic salts,adding MgSO4 and KH2PO4 into medium could promote the mycelium growth,and ZnSO4,however,inhabited the spread of mycelium.
Keywords:Pleurotus eryngii  carbon sources  nitrogen sources  inorganic salts  mycelium growth rate  mycelium growth vigor
