Effect of addition of corn fiber in the medium on the fruit-body production of edible mushrooms

Abstract

　Corn fiber, the waste product of corn starch manufacture, was studied to estimate its applicability as a substrate for the commercial production of several edible mushrooms in Japan by bottle cultivation. The use of corn fiber successfully increased the yield of fruit-bodies (fresh weight basis) of Pleurotus ostreatus, P. sajor-caju, Pholiota nameko and Hypsizygus marmoreus by 1.02～1.31 times when it was added to the basal medium (10～30%) consisting of sawdust and rice bran.
