The bacterial strain a thermophilic carboxymethyl cellulase-producing was screened from biocompost. The strain was identified as Bacillus sonorensis CY-3 according to morphological, biochemical and molecular analysis, then it was optimized for the production of carboxymethyl cellulase (CMCase).

Cellulose constitutes bulk of the plant cell wall materials and the most abundant and renewable non-fossil carbon source on earth. Cellulose degrading fungi play an important role in recycling of cellulosic materials. Thus, this study was designed to screen endophytic fungi isolated from Cameroonian medicinal plants for their cellulase activity. The plate-clearing assay and enzyme assay methods were used for screening of potent cellulolytic endophytic fungi. The promising was chosen for filter paper cellulase (FPCase) and carboxymethyl cellulase (CMCase) assay.

Characterization of cellulolytic microorganisms associated with naturally decomposing waste material
Thirty four samples of naturally decomposing waste material were collected from rural and urban parts of Western Maharashtra from which 64 bacteria, 49 fungi and 63 actinomycetes strains were isolated. The isolates were screened for cellulolytic activity on Czapek’s mineral salt agar media amended with carboxymethyl cellulose. Seventeen bacteria, thirty fungi and fifty seven actinomycetes isolates showed zone clearance indicating cellulase enzyme activity.

A carboxymethyl cellulase enzyme was prepared from a wild type strain of Aspergillus niger Z10. Analyses of the enzyme preparation by SDS-PAGE revealed two protein bands showing cellulolytic activity. The molecular weight of these bands was estimated to be around 83,000 and 50,000.

The basidiomyceteCoprinopsis cinereaproduces the glycoside hydrolase family 6 enzyme CcCel6C at low and constitutive levels. CcCel6C exhibits unusual cellobiohydrolase activity; it hydrolyses carboxymethyl cellulose, which is a poor substrate for typical cellobiohydrolases. Here, we deter-mined the crystal structures of CcCel6C unbound and in complex with p-nitrophenyl b-d-cellotrioside and cellobiose.
