茶新菇菌丝体液体深层发酵研究

Liquid Depth Fermentation of Chaxingu Mushroom (Agrocybe aegerita) Mycelia

以菌丝体生物量为最终发酵目的,利用正交试验的方法,筛选出茶新菇深层发酵培养基最佳配方:玉米粉3%、蛋白胨1%、KH2PO40.3%、MgSO40.1%,初始pH值为6时生物量最大,干重可达18.6～19.0g/L,接种量以增殖期的5%～10%为宜。

An optimum formula of medium for depth fermentation of chaxingu mushroom (Agrocybe aegerita) was screened through orthogonal experiment methods with the biomass of mycelia as the final fermentation goal. It was 3% corn meal, 1% peptone, 0.3% KH-2PO-4, and 0.1% MgSO-4; when initial pH was 6 the biomass was the highest, and the dried weight hit up to 18.6～19.0 g/L. And the inoculation should be 5%～10% of the proliferation phase.
