Abstract

New plant growth inhibitors, substances A-79197-2 and -3, were found to be produced by strain SANK 61299 isolated from fresh plant leaves. Strain SANK 61299 was identified as Dacthylosporangium aurantiacum. Substances A-79197-2 and -3 were determined to be di- and tri- saccharides of streptol, an active ingredient, respectively. Streptol related compounds have been found as components of plants.
