Structure Characteristics of Antibacterial Compound Isolated from the Secondary Metabolites from Streptomyces roseogilvus var. marinus

摘要

An antibacterial compound was isolated and purified from the secondary metabolites of the Streptomyces roseogilvus var. marinus strain and structure anlysis by ESI-MS and NMR. The results showed that molecular formula of antibacterial compound was C₂₂H₂₇O₇N₃S, and its molecular structure agreed well with griseoviridin producing from terrestrial microorganisms. Streptomyces roseogilvus var. marinus is a new potential griseoviridin-producing strain by our knowledge. It is first reported that griseoviridin is isolated from the marine-derived actinomycete.
