More than three hundreds microorganisms to hydrolysis carboxylmethylcellulsoe (CMC) were isolated from the seashore of the Kyungsang province in Korea. Among them, twelve microorganisms showed relatively higher activity of cellulase. Activity expressed as unit of cellulase by twelve microorganisms ranged from 35 to 110 unit with the liquid medium containing 2.0%(w/v) glucose, 0.25% yeast extract, 0.5% K2HPO4, 0.1% NaCl, 0.02% MgSO4·7H2O and
0.06% (NH4)2SO4 at 30°C for 72 hr under aerobic conditions. The best carbon source and nitrogen sources for the production of cellulase by P.aquimaris LBH-10 were found to be rice bran and peptone. CMC, Filter paper, Avicel and pNPG activities of the cellulase produced by P.aquimaris LBH-10 with 2.0%(w/v) rice bran and 0.5%(w/v) peptone were 929.97, 109.04, 94.37 and 4.38 unit for 72hr respectively.
