SUBSTRATE FOR CULTURING XYLOTROPHIC BASIDIOMYCETES AND A METHOD FOR PRODUCTION THEREOF USING METHODS OF CHEMICAL MODIFICATION OF LIGNOCELLULOSE MATERIAL Russian patent published in 2019 - IPC A01G18/20 

FIELD: biotechnology.

SUBSTANCE: group of inventions relates to biotechnology and can be used to produce fruit bodies of basidiomycetes. Disclosed are a method of preparing selective substrates and a selective substrate for producing fruit bodies of basidiomycetes. Method involves acid modification of lignocellulose raw material - agricultural wastes and wood processing industry – with aqueous solutions of mineral or organic acids with concentration of 0.5–5 wt%. at temperature of 80–135 °C and ratio of raw material to acid solution from 1:2 to 1:8 for 30–60 minutes, washing with water and adding to modified lignocellulose material nitrogen source in concentration of 10–20 wt% and chalk or gypsum in concentration of 2 wt% The selective substrate is obtained using said method.

EFFECT: inventions provide higher yield of fruit bodies of basidiomycetes.
