Abstract
The effect of cellulosic substrates on the production of extra-cellular cellulases and their cellulolytic activity inChaetomium globosum has been studied in shake flask cultures. Production of endoglucanase, exoglucanase and filter paper cellulase was highest with pure cellulose whereas β-glucosidase was maximally induced by wheat straw. A suitable pretreatment for wheat straw was peracetic acid followed by NaOH and that of bagasse with NaOH for saccharification.
Résumé
On a étudié l'effet de substrats cellulosiques sur la production de cellulases extracellulaires et leur activité cellulolytique chezChaetomium globosum en culture en flacons agités. La production d'endoglucanase, d'exoglucanase et de cellulase type papier-filtre est maximum avec la cellulose pure tandis que la β-glucosidase est induite de manière maximum par la paille de froment. La paille de froment est traitée de manière adéquate pour la saccharification par l'acide peracétique suivi de NaOH, la bagasse, par NaOH.
