title: [New antibiotic, parvulomycin, produced by a culture of Actinomyces parvullus var. chromogenes var. nov].
abstract: Actinomycete LIA-O784 was isolated from a soil sample. By its morphological and cultural properties the isolate was close to Act. parvullus but differed from it in synthesis of melanoid pygment, thyrosinase, hydrogen sulphide and pronounced antifungal activity. The actinomycete was classified as a new variant and designated as Actinomyces parvullus var. chromogenes var. nov. The culture produced a new polyglycoside antibiotic named parvulomycin. The physico-chemical characteristics of the antibiotic is presented.
