Abstract

Clostridium Papyrosolvens producing filter paperase, carboxymethyl cellulase and cellobiase under anaerobic cultivation conditions at 35 °C is described. Higher activities of filter paperase and carboxymethylcellulases were assayed in 48 h culture filtrate, while maximum cellobiase accumulated in the culture broth at 72 h. Filter paperase, carboxymethylcellulase and cellobiase activities were optimum at 35 °C and pH values of 7.0, 6.5 and 7.5 respectively. Cultivation of the strain in 1000 ml Hungate bottles with 1% cellulose at pH 6.5 and 35 °C produced carboxymethyl cellulase, filter paperase and cellobiase activities of 45, 35 and 20 IU/ml respectively.
