title: [Isolation and physicochemical study of the components of the new antibacterial antibiotic 2562].
abstract: An antibacterial antibiotic complex consisting of 2 components designated as 2562 A and 2562 B is produced by Streptomyces griseovarabilis. The antibiotic was isolated from the mycelium and purified chromatographically on a column with aqueous silicic acid. The study of the components showed that component 2562 A was chlorbiocin, while component 2562 B differed from the known antibiotics of this group. Physicochemical assays demonstrated that component 2562 B differed from chlorbiocin by the absence of the methyl group in pyrrol, which is probably attached to sugar at beta-position. It was found that component 2562 B is a new representative of the antibiotic cumero-glycoside group.
