title: [Polymorphism of a culture of the chromomycin producer, Actinomyces aburaviensis var. verrucosus].
abstract: Polymorphism of the chromomycin-producing orgnaism Act. aburaviensis var. verrucosus 144--3 was studied. The stable variants differed in the morphologo-cultural properties, assimilation of the carbon sources, the component composition of the luminescence substances and the quantitative property of the antibiotic production. A substance with violet luminescence was found in the culture of varient I in addition to chromomycin. Similarity of the phenotypes observed in variants 1 and 2 when grown on complex organic media is explained by intensive chromomycin production by variant 1 on such media. Active colonies may be selected according to the colour due to chromomycin. Forms with an activity almost 4 times higher than that of the initial culture were found among the colonies of variant 2.
