Abstract
In order to produce alkaline protease, psychrotrophic Bacterium which have high enzyme activity, was isolated by using enrichment culture from soil samples and identified as genus Bacillus sp. The optimal pH and temperature for the enzyme activity were pH 6 and
토양시료로부터 높은 활성의 pretense를 생산하는 세균을 수십종 분리하였다. 분리된 세균중에서 protease활성과 성장속도면에서 가장 우수한 균주를 선별하여 WRD-2로 명명하였으며, 형태학적, 생화학적 및 생리학적 특성을 조사한 후 Bacillus sp로 동정되었다. WRD-2조효소액의 protease 최적 활성은 pH 6.0, 온도는
