摘要: While screening for cellulase-producing fungi from insect gut, a fungus with high endoglucanase (carboxymethyl cellulase; CMCase) activity was isolated from the larval gut of Bombyx mori. Based on morphological characteristics and using an 18S rRNA-based molecular phylogenetic approach, the fungus, strain BMC-2, was identified as a Mucor sp. expressing a novel alkalotolerant cellulase. The maximum production of cellulase by the BMC-2 strain was observed at 55 degrees C and pH 8.0. The CMCase activity was inhibited by Cu2+ > Na+ > Zn2+ > Mg2+ > Ba2+, and induced by Ca2+, Mn2+, Fe2+, and K+.
