Abstract

The invention relates to the field of regeneration and recycling of wastes and provides a harmless treatment method for gliotoxin mushroom dregs. The modified treatment utilization method of the gliotoxin mushroom dregs comprises the following steps: treating residual gliotoxin mushroom dregs; by taking the treated mushroom dregs as a main raw material and other agricultural byproducts as auxiliary materials, inoculating a selective multiple microorganism solid to ferment; and then performing drying, crushing and sieving, packaging and the like. The treatment method has the characteristics of being simple in production process, easy to operate, short in treatment time and the like. The proteins of a modified product is greater than or equal to 25%, and can be re-used for fermenting culture of gliotoxin, so that the invention provides a novel path which solves the environmental pollution and waste material recycle in gliotoxin production.

Description

technical field [0001] The invention relates to the field of solid waste recycling, and relates to a harmless treatment method for gliomycin slag. Background technique [0002] Gliomycin is an epipolythiopiperazine diketone toxoid, which is a secondary metabolite of fungi such as Trichoderma. It is a low molecular weight polar sulfur bridge type compound. Weidling and Emerson (1936) first separated this substance from Trichodermalignorum, Weidling named this substance gliotoxin (gliotoxin), and its structure was identified by Bell et al. in 1958. [0003] At present, gliomycin mainly produces agricultural biofungicides through liquid submerged fermentation of Trichoderma viride, and is mainly used for soil-borne diseases such as cotton wilt, rice sheath blight, rape sclerotinia, apple rot, grape anthracnose, pepper anthracnose, etc. prevention and treatment. Because of its good killing and inhibitory effects on soil-borne disease pathogens, it has become a hot research to...
