#### Abstract

When the enzyme preparations were at various temperatures for 1 hour, the thermal stability for the enzyme was maximum at $30{\circ}C.$ The optimum temperature for the enzyme activity was at $40{\circ}C.$ When the enzyme preparations were exposed to various pHs for 22 hours, the enzyme stability was maximum at pH 3.8, and it was decreased gradually as the pH rose up to 4.8, above which the stability was greatly restored. When the exposure period was extended from 22 to pH's 3.0 and 5.9, but the stability tended to rise at pH's below 3.0 and above 5.9. The optimum pH for the enzyme activity was obtained at 4.8.
