Abstract: A new species of Micromonospora, designated Micromonospora lacustris sp. nov. Routien, when subjected to submerged aerobic fermentation under controlled conditions, produces a mixture of at least 13 antibiotics. Two of these antibiotics are rifamycin S and rifamycin SV. Two other members of the antibiotic mixture are the 3-thiomethyl derivatives of rifamycin S and rifamycin SV.
