| Research Abstract |
Subtilase and cellulase exhibited hydrolytic activity toward carboxymethyl cellulose with optimum temperature and pH at 30 °C and pH 8.0, respectively. The thermal stability was characterized and temperature at which activity decreased to50% by the 30 min treatment at pH 7.0 was 32 °C. The isolated cellulase activity was remained at high level at 5-20 °C which is growth temperature of the short-spined sea urchin. Thus, we confirmed that a cellulase of the short-spined sea urchin is adaptiveenzyme around low water temperature.
