Lipopeptides from actinoplanes sp. with pharmacological action, process for their production and the use thereof

摘要

The invention relates to lipopeptides with very homologous amino-acid sequences but different fatty acid residues (lipid portion) which are synthesized by Actinoplanes sp. during fermentation and are released into the culture medium, to a process for isolating the lipopeptides from the culture medium and purifying them, to the use of the lipopeptides as pharmacologically active substances, in particular against Gram-positive bacteria, and to Actinoplanes sp. DSM 7358 for producing the abovementioned lipopeptides.
