概要

Neurospora sitophila was cultured in the media, which contained comparatively much pentose, prepared from waste sources, i. e. hydrolysates of rice hull, rice and wheat-straw, corn cob and rice bran, filtrate of distiller's waste liquor and rice bran extract.The yield of fungus and the rate of sugar consumption were better in the hydrolysates of rice straw and rice bran and rice bran extract than in the other media. The rate of sugar consumption in the above three media was more than 90%.Addition of inorganic salts ((NH_4)_2SO_4 5%, KH_3PO_4 1%, MgSO_4・7H_2O 0.5%) to every medium brought good effect upon the yield of fungus and the pigment production, especially in the hydrolysates of rice hull and corn cob.When this fungus was cultured in the filtrate of distiller's waste liquor, carbohydrates contained in the medium would be decomposed to reducing sugar by the enzymes produced by this fungus, and then assimilated.
