โฆ Synopsis
The extracellular carboxymethyl cellulase (CMCase) was purified 17-fold from Micrococcus roseus, a symbiotic organism of higher termites. Purified CMCase had an M r of 45 kDa and was optimally active at pH 8.0 and 40ยฐC. Carbohydrate was associated with it and cellobiose was a competitive inhibitor of its activity.

A newly isolated Bacillus species, which grew optimally at 30ยฐC and pH 10, produced a carboxymethylcellulase in a medium containing 10 g CM-cellulose/l. The enzyme, when partially purified by gel filtration, had a mass of about 29 kDa as determined by both SDS-PAGE and gel filtration chromatography.
