 note = {application/pdf, High cellulase activity was detected in the extract of marine gammarid amphipods inhabiting sea weed beds. The cellulase was partially purified by ammonium sulfate precipitation and successive column chromatographies. One of the two fractions separated by Sephadex G-100 gel chromatography was C₁-cellulase (correspond to avicelase, E. C. 3. 2. l. 91), which hydrolyzed more insoluble cellulose, avicel and filterpaper, than soluble cellulose, carboxymethylcellulose. The other was Cx-enzyme (correspond to　CMCase, E. C. 3. 2. 1.4), which cleaved more soluble carboxymethylcellulose. Both enzymes had pH　optimum of around 5.5, and was fairly stable in a pH region of 5.0 to 8.0 for 20 hr at 30℃ and was　completely stable below 40℃ for 30 min-incubation at pH 7.0. C₁-and Cx-enzymes had molecular weights of approximately 34,000 and 26,000, respectively. These cellulase were estimated to originate from gammarids in the sbsence of cellulolytic symbiotic bacteria.},
