MUSHROOM BED FOR SHIITAKE (LENTINULA EDODES)

摘要

PROBLEM TO BE SOLVED: To solve a problem, annoying the farmers producing Shiitake when cropping and delivering Shiitake to the market, of how to deal with Shiitake stems generated as by-product when preparing Shiitake as a commodity, by applying the method in which fermentation of Shiitake stems is promoted by using water and an acid aqueous solution, then Shiitake stems are subjected to alcoholic fermentation and distillation by yeast to generate ethyl alcohol.SOLUTION: Shiitake stems are a by-product when cultivating and preparing them as a commodity. The Shiitake stems, and water and an acid aqueous solution (citric acid, succinic acid, tartaric acid, ascorbic acid, and malic acid) are uniformly mixed in a weight ratio of 1:5 to 1:100, the fermentation of the Shiitake stems being promoted, and are heated for 30 to 60 minutes. The Shiitake stems, after being processed, become ethyl alcohol and a fermentation residue which is to be reused as a material for a mushroom bed when cultivating Shiitake. Thus a zero-emission method generating no waste disposal is obtained.
