Abstract

In order to develope a new pretense applicable to industries, a bacterium which produces a remarkable amount of extracellular pretense were isolated from soil. About 10 bacterial strains producing pretense were isolated from samples of soil, and strain PANH765 showed the highest activity of pretense production among them. The strain was identified as Bacillus subtilis according to the Bergey's Manual of Systematic Bacteriology based on its morphological, cultural and physiological characteristics. B. subtilis PANH765 showed the maximal production of pro-tease in the medium containing 2.0% glucose, 1.0% yeast extract, 0.2% ammonium nitrate, 0.02% ferrous sulfate and 0.02% dipotassium hydrogen phosphate. Under the optimal condition with temperature of 3$0^{\circ}C$, initial pH of 7.0 and shaking speed of 150 rpm, the pretense production reached a maximum level with 36 hr cultivation (6.34 U).

공업적으로 광범위하게 이용되고 있는 protease 중 중성 영역에서 최적의 활성을 갖는 중성 protease에 대한 연구의 일환으로, 토양으로부터 protease의 생성능이 우수한 10여 균주를 순수 분리하였으며, 이들 중에서 protease의 활성 이 가장 우수한 PANH765를 최종 선별하였다. 이 균주의 형태학적, 배양학적, 생리학적 및 생화학적 특성을 조사하여 Bergey의 세균 분류서의 색인에 따라 체계적으로 분류한 결과, Bacilius subtilis 또는 그 유연균으로 동정되어 분리균을 Bacilius .Subtilis PA-NH765로 동정하였다. B. subtilis PANH-765 균주에 의한 protease의 최적 배지 조성은 2.0% glucose, 1.0% yeast extract, 0.2% ammonium nitrate, 0.02% ferrous sulfate 및 0.02% di-potassium hydrogen phosphate이었으며, 최적 생산 조건은 배양온도 ,3$0^{\circ}C$, pH 7.0, 진탕 속도 150 rpm이었다. 이 조건에서 초기 균체량을5%(w/v)접종하여 배양하였을 때 시간에 따른 효소의 최대 활성은 배양 ,36시간일 때 6.34 U이었다.
