  • Patent number: 7785826
    Abstract: The invention relates to a method for the enzymatic elimination of the N-acyl side chain from lipopeptides to form the corresponding nucleus, wherein the lipopeptide is prepared by fermentation, the lipopeptide being bound to the cells of the biomass, and the biomass is removed with the adhering lipopeptide, the biomass with the adhering lipopeptide is resuspended in an aqueous system, a suitable deacylase is added in dissolved or solid form to the suspension of the biomass, and the corresponding nucleus is formed, and the nucleus is optionally isolated and purified, wherein the lipopeptide obtained by fermentation is reacted after the end of the fermentation as cell-bound biomass without further purification directly with a deacylase, whereby the N-acyl chain linked via an amide linkage is eliminated.
