ABSTRACT Thailand is an agricultural country - producing tons of agricultural waste rice straw - corncobs - coconut husk - sugarcane bagasse - cassava peel - and peanut hulls Instead of eliminating - these biomasses can be converted to a value-added product - cellulase enzyme for industrial sector Peanut hulls are one of excellent sources for cellulose - which can be used as a carbon source for microbial cellulase production This study is conducted by experimental design using pretreated peanut hulls as a substrate via solid-state fermentation SSF by white-rot fungus - Pycnoporus sanguineous The three treatments 1 initial moisture in solid substrate 60% - 70% - 80% - and 90% - 2 temperature 25oC - 30oC - and 37oC - and 3 initial pH value 5 0 - 5 5 - 6 0 - 6 5 - and 7 0 on cellulase production in 3–12 days of incubation were observed in flask fermentors The highest productions were obtained on the 9th day of incubation at 70% initial moisture - 30oC - and initial pH 6 0 The enzyme activities of filter paper activity FPase - carboxymethyl cellulase CMCase and cellobiase were 4 437?0 148 - 11 433?0 144 and 0 890?0 087 unit per gram dry substrate U/gds respectively These results supported that the cellulase production by P sanguineous under SSF using pretreated peanut hulls as a substrate could be an alternative choice for commercial cellulase production


Abstract :

ABSTRACT Thailand is an agricultural country - producing tons of agricultural waste rice straw - corncobs - coconut husk - sugarcane bagasse - cassava peel - and peanut hulls Instead of eliminating - these biomasses can be converted to a value-added product - cellulase enzyme for industrial sector Peanut hulls are one of excellent sources for cellulose - which can be used as a carbon source for microbial cellulase production This study is conducted by experimental design using pretreated peanut hulls as a substrate via solid-state fermentation SSF by white-rot fungus - Pycnoporus sanguineous The three treatments 1 initial moisture in solid substrate 60% - 70% - 80% - and 90% - 2 temperature 25oC - 30oC - and 37oC - and 3 initial pH value 5 0 - 5 5 - 6 0 - 6 5 - and 7 0 on cellulase production in 3–12 days of incubation were observed in flask fermentors The highest productions were obtained on the 9th day of incubation at 70% initial moisture - 30oC - and initial pH 6 0 The enzyme activities of filter paper activity FPase - carboxymethyl cellulase CMCase and cellobiase were 4 437?0 148 - 11 433?0 144 and 0 890?0 087 unit per gram dry substrate U/gds respectively These results supported that the cellulase production by P sanguineous under SSF using pretreated peanut hulls as a substrate could be an alternative choice for commercial cellulase production
