Abstract

The purplish-red pigment was formed on agar plate by superimposed streaking of Streptomyces propurpuratus ATCC 21630 and strain R-89, The strain No.89 was ascribable to the genus Bacillus and designated as Bacillus sp. R-89. Both strain did not produced such pigment when cultivated independently. For hyperpigment production, we selected the mutant S.P-6 from Streptomyces propurpuratus ATCC 21630 by MNNG (N-methyl-N'-nitro-N-nitrosoguanidine) treatment. Maximum purplish-red pigment 1420 mg/$m\ell$ were produced, when the mutant of R-16 and Bacillus sp. R-89 were mixed cultured at 3$0^{\circ}C$ for 72 hr.

미생물에 의한 적자색 색소를 생산하기 위하여 Streptomyces propurpuratus ATCC 21630과 토양에서 분리한 strain No.89를 한천배지상에서 혼합배양하여 적자색을 형성하였다. 적자색 색소를 형성하는 strain No89는 Bacillus sp. R-89로 명명하였다. 이들 두 균주는 각각 배양하였을 때는 색소를 형성하지 않았다. 적자색 색소를 많이 생산하기 위해 Streptomyces Propurpuratus ATCC 21630를 MNNG (N-methyl-N'-nitro-N-nitrosoguanidine) 로 처리하여 얻은 변이주 S.P-6과 Bacillus sp. R-89를 생산배지에서 혼합하여 발효하였을 때 1420$\mu\textrm{g}$/$m\ell$의 색소를 얻을 수 있다.
