title: [New species of actinomycete Streptomyces variegatus sp. nov. synthesizing an antibiotic of the alpha-hydroxyketopentaene group].
abstract: Stroptomyces strains INA T-511 and INA 3946 were isolated from 2 different soil samples. Both the strains produced an antibiotic of the group of alpha-hydroxyketopentaenes. The antibiotic was active against gram-positive bacteria, yeasts and fungi belonging to Penicillium. In addition, the strains produced a pigment antibiotic of the prodigiosin type and a pigment identified as ferroverdin. The study of the cultural and morphological features and the natural variation of the strains has shown that they belong to a new species, designated as Streptomyces variegatus sp. nov. Sveshnikova et Timuk.
