研究不同碳源、氮源及无机盐对金针菇菌丝体产量的影响,采用正交设计法进行金针菇液态发酵培养基配方筛选和优化,确定了最佳培养基配方为大米粉3%、酵母粉1%、KH2PO4 0.1%、MgSO4·7H2O 0.05%.同时利用此配方培养测定了发酵过程pH、还原糖和氨基氮含量的变化,结果表明:发酵过程中pH变化很小,培养末期略有上升;还原糖含量呈先增后降的变化,氨基氮含量呈上升趋势.

Different carbon source,nitrogen source and KH2PO4,MgSO4·7H2O impact on out put of mycelium of Flammulina velutipes of density are studied in this text,the best prescription is ： rice powder 3%,yeast 1%,KH2PO4 0.1%,MgSO4·7H2O 0.05% and glucose 1%,VB1 10μg/ml,VB2 50μg/ml.At the same time the changes of pH,reducing sugar,amino ammonia content are determined in the fermented course.The result shows that the change of pH is very small,and slightly rise in latter stage;the content of reducing sugar presents the change, that lowe...
