Antibiotic A/16686 and process for preparation thereof

摘要

The present invention relates to a glycopeptide antibiotic arbitrarily designated as A/16686 antibiotic, and to its physiologically-acceptable acid addition salts. Antibiotic A/16686 free base, and its acid addition salts are antibacterial agents, especially active against grampositive microorganisms. The process for producing antibiotic A/16686 by culturing a novel strain of the Antinoplanes genus, designated as Actinoplanes sp. ATCC 33076, is a further object of the present invention.
