The isolation of lavendamycin (1) an antibiotic closely related to streptonigrin (2) is described. Details of the taxonomic description of S. lavendulae (strain C-22,030), production of lavendamycin, its isolation and the biological activity are given. Recently we have reported the structure determination of lavendamycin (1), a novel antibiotic closely related to streptonigrin (2) in structure (Fig. 1).1) In this paper we report the characterization of the producing culture, the fermentation conditions, the isolation of, and biological activity of 1.
