title: [Actinomyces pneumonicus var. altamicus var. nov., a producer of new altamycin antibiotics].
abstract: Actinomycete LIA-0788 was isolated from a soil sample. By its morphological and cultural features the actinomycete was close to Actinomyces pneumonicus and differed from it in the antibiotic properties. This provided classification of actinomycete LIA-0788 as Act. pneumonicus var. altamicus var nov. The culture produced altamycins A and B, new antibiotics. Their physico-chemical characteristics is presented.
