[Actinomyces fulvoviolaceus ver. achromogenes var. nov., a producer of the new heptaene complex, fulvomycin].
An actinomycetous culture designated as LIA-0721 was isolated from a soil sample. It was close to Act. fulvoviolaceus by its morphologo-cultural features and differed from it in production of melanoid pigments and the spectrum of carbohydrate assimilation. This justified its classification as Act. fulvoviolaceus var. achromogenes var. nov. The culture produced new aromatic heptaens, i. e. fulvomycins A, B and C. Their physico- chemical and biological characteristics are presented.
