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.

Abstract: New 3-thioethers of rifamycin SV are prepared by the reaction of rifamycin S with appropriate mercaptans. These thioethers of rifamycin SV are oxidized to yield the corresponding thioethers of rifamycin S. All these compounds exhibit significant antibiotic activity.
Abstract translation: 利福霉素SV的新3-硫醚通过利妥霉素S与适当的硫醇的反应来制备。 利福霉素SV的这些硫醚被氧化以产生相应的利福霉素S的硫醚。所有这些化合物都显示出显着的抗生素活性。
