摘要: 本实验采用平板培养和液体培养方法,研究了不同矿质元素的浓度对黄伞菌丝生长和胞外多糖产量的影响。单因素试验结果表明,适宜黄伞平板菌丝生长的最佳矿质浓度为:0.5% NaNO3、0.05% Na2HPO4、0.012% FeSO4、0.24% MgSO4、0.018% ZnSO4;适宜黄伞液体培养产胞外多糖的最佳浓度为:0.70% NaNO3、0.05% Na2HPO4、0.006% FeSO4、0.20% MgSO4、0.006% ZnSO4;适宜黄伞液体培养产菌丝的最佳浓度为:0.5% NaNO3、0.05% Na2HPO4、0.012% FeSO4、0.24% MgSO4、0.018% ZnSO4。

Abstract: The plate culture and liquid culture were adopted to investigate the effects of different concentrations of several mineral elements on the exopolysaccharide production and mycelial growth of Pholiota adiposa in this study. The results of monofactorial analysis showed that the optimal concentrations of several mineral elements for mycelial growth on plate medium are NaNO3 0.5%,Na2HPO4 0.05%,FeSO4 0.012%,MgSO4 0.24%,and ZnSO4 0.018% respectively; As far as liquid culture is concerned,the optimal concentrations for producing exopolysaccharide are NaNO3 0.70%,Na2HPO4 0.05%,FeSO4 0.006%,MgSO4 0.20%,and ZnSO4 0.006% respectively,and the optimal concentrations for mycelial growth are NaNO3 0.5%,Na2HPO4 0.05%,FeSO4 0.012%,MgSO4 0.24%,and ZnSO4 0.018% respectively.
