A Bacillus strain was isolated from waste pulp.The strain had high endo β glucanase producing ability proved by the Congo red dying method on the culture plates.Optimal growing conditions of the strain were 35~37?℃,pH 9.0~10.0.Results in shaking flask culture showed that high cellulase activities(CMCase)could be detected in both neutral and alkali conditions from the fermentation broth,and the neutral and alkali cellulase activities were 69.4?U/mL and 53.6?U/mL,respectively.The optimal conditions for ...
