초록
전통 대두발효식품으로부터 색소 생성능과 protease 활성이 가장 강한 균을 선별하여 Bacillus sp. CS-l7로 동정하였다. CS-17 균의 균체증식은 배양 24시간, protease 활성은 배양 48시간, 그리고 색소 생성은 배양 72시간 후 최대에 달하였다. Bacillus sp. CS-17은 대두분말을 1.0% 첨가한 색소 생성용 기본배지에서 가장 높은 색소 생성능을 가지는 것으로 나타났다. 배양조건이 Bacillus sp. CS-17의 색소 생성에 미치는 효과를 조사한 결과, pH 8.5에서
A bacterium with potent activity of pigment production and protease was isolated and identified as being Bacillus sp. CS-17. Cell growth, protease activity and pigment production of the strain reached to its maximum point after 24 hrs, 48 hrs, 72 hrs, respectively. The best pigment producing ability of Bacillus sp. CS-17 was shown on basal medium for pigment production added 1.0% soybean. The high effcient conditions for pigment production was obtained at culture of pH 8.5,
