Abstract
Spontaneous variants of the beromycin-producing strainStreptomyces glomeratus 3980 were divided into five groups (A-E) according to increasing antibiotic activity. The most active variants (group E) differed from the other types and the wild strain by a suppressed ability to produce aerial mycelium and melanoid pigment and by an increased production of propionic acid. Strains with a 12-fold higher antibiotic production capacity (with respect to strain 3980) were obtained by selection of superior segregants from submerged cultures of the E type.Keywords
