METHOD FOR CULTURING A BASIDIOMYCETOUS FUNGUS IN A LIQUID CULTURE MEDIUM

摘要

Disclosed is an efficient method for culturing an edible basidiomycetous fungus such as Mushroom Agaricus Blazei Murill in a liquid culture medium to give fungus aggregates of several centimeter size. Characteristically, the liquid culture medium is formulated with sucrose as a carbon source in the form of crude cane sugar in combination with a water-insoluble growth- supporting material in the form of a fine powder to serve as the core of the fungus aggregates as selected from crushed sugarcane, sugarcane bagasse, pin e trees and wheat bran. Further characteristically, the culturing procedure is carried out under an oxygen-enriched condition by blowing oxygen-enriched ai r of at least 30 % by volume oxygen into the culture medium under pressurizati on at 0.12 to 0.5 MPa (absolute) in a specified blowing rate.
