✦ Synopsis

Cellulases and fl-glucosidase were produced by Neurospora sitophila cultured in media containing corn stover or sugar cane bagasse as carbon sources. The effects of initial medium pH, organic nitrogen source and Tween 80 on enzyme activity were investigated. Values of pH above 6.5 were found to favour enzyme production. Defatted sesame seed flour increased both carboxymethylcellulase and filter-paper activities, while yeast extract enhanced fl-glucosidase activity. Tween 80 at a concentration of 0"1% (v/v) increased all the enzyme activities.
