Association of Aspergillus fumigatus with sugar-cane bagasse, biochemical and physiological studies

Abstract

Aspergillus fumigatus degraded sugar-cane bagasse better than wheat and paddy straw. In liquid cultures it produced cellulase, xylanase, pectinase and protease when provided with sugar-cane bagasse, wheat and paddy straw as carbon sources. Enzyme production was higher on bagasse than on wheat and paddy straw. Maximum growth occurred on glucose and xylan and minimum on carboxymethyl cellulose when used as sole carbon sources. Production of cellulase and xylanase was maximum on xylan, pectinase on pectin and protease on glucose. Neither cellulase nor pectinase activity was detected in glucose medium.
