Abstract

The invention relates to a culture medium for the liquid fermentation of edible and medicinal fungi. The culture medium comprises KH2PO4, MgSO4, sucrose, peptone and corn residue, wherein the corn residue is replaced by one of rice bran, sorghum flour, wheat grains and wheat bran. The obtained culture medium has low cost and high economic value.

Description

technical field [0001] The invention relates to a culture medium for liquid fermentation of edible and medicinal fungi. Background technique [0002] Edible and medicinal fungi are an important biological resource. my country is the country with abundant edible and medicinal fungus resources in the world, and it is also the first country in the world to utilize edible and medicinal fungus resources. Its germplasm resources are very rich, but development and utilization are relatively Later than animal and plant resources. The production of edible and medicinal fungi can use the by-products or wastes of animal and plant industries as raw materials, which is an important part of ecological agriculture. With the continuous improvement of living standards, people's demand for edible and medicinal fungi will increase greatly. However, the traditional cultivation and production methods are far from being able to meet the growing needs of the edible and medicinal mushroom industry...
