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). | A novel alkaline highly thermostable and oxidant resistant Carboxymethyl Cellulase Cmcase Produced by thermophilic Bacillus sonorensis CY-3
