Abstract: This study presents effects of some nutritional and environmental factors on cellulases production by isolates, Bacillus licheniformis WBS1 and Bacillus sp. WBS3, which have been isolated from an Indian hot spring. Activity of both CMCase and FPase were higher in case of wheat straw. Maximum enzymatic activity was found at following optimum parameters: pH (8.0when grown on rice, 9.0 when grown on wheat); temperature, 60°C; and incubation period, 60 h. In addition, combination of inorganic and organic nitrogen source was found to be most suitable for cellulases production.
