Isolation of a Pigment Producing Marine Strptomyces sp. from Shallow-sea Muds around in Korea

한국 근해 연안저토에서 분리한 해양 방선균이 생성하는 색소의 분리

A marine Streptomyces sp., which produce water-soluble blue pigment was isolated from shallow-sea muds. The effect of various nutritional conditions on growth of isolated strain were investigated to facilite the potential use of this organism in industry. The effect of carbon source was characterized as a 10g/1 of soluble starch. Growth was optimum at pH 7.0 and slightly affected with more alkaline range but was shown to decrease dramatically in acidic range. Under the optimum growth conditions, isolated strain produced substantial amounts of blue pigment and biomass.

공업적 응용 가능성을 검토하기 위하여 한국의 근해 연얀저토에서 분리한 청색색소를 생성하는 Streptomyces sp.의 성질을 조사하였다. 탄 소원은 가용성 전분으로서 1% 였고, pH 7.0 이 상의 약 얄칼리성에셔 최대성장을 하였으며, 다량의 청색색소를 생생하였다.
