By using bagasse hydrolysate as the culture medium of Neurospora sitophila, various effects on the growth and the pigment production of it were examined.1) As the pretreatment method of bagasse hydrolysate, it was most favourable for the growth and the pigment production to treat it with 0.5〜1% active carbon for 10〜20 min. at 60℃.2) The amounts of (NH_4)_2SO_4,KH_2PO_4,MgSO_4・7H_2O fitted for the growth were 20〜40%, 2〜10%, 0.25〜0.75% of the sugar, respectively.Potassium salt produced good effect upon the pigment production.3) As the neutralizing reagent of the hydrolysate, ammonia was fitted for the growth.4) The sugar concentration of the hydrolysate fitted for the growth was 1.2〜1.6%, but the pigment production increased with sugar concentration.5) By decomposing in autoclave so far as 5th step discontinuously with H_2SO, 49.34% reducing sugar to the bagasse was obtained.6) Of the eleven kinds of hydrolysates (No. 1〜11) used as culture medium, the primary hydrolysates of pentosan and fiber in bagasse, and their mixtures were fitted for the growth and the pigment production.
