Studies on marine microorganisms. V. A new antibiotic, aplasmomycin, produced by a streptomycete isolated from shallow sea mud.

Abstract
A new antibiotic, aplasmomycin, which inhibits growth of gram-positive bacteria including mycobacteria in vitro, and plasmodia in vivo was obtained from a strain of Streptomyces griseus isolated from shallow sea sediment in Sagami Bay [Japan]. The antibiotic forms colorless needle-like crystals and has a molecular formula of C41H60O14Na. Based on its physical and chemical properties, aplasmomycin was concluded to be a new antibiotic. The antibiotic was produced in selected media devised to relate to a marine environment.
