    • 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.
    • 本发明涉及从脂肽酶消除N-酰基侧链以形成相应核的方法,其中脂肽通过发酵制备,脂肽与生物质的细胞结合,并且用 将附着的脂肽,具有粘附的脂肽的生物质重新悬浮在水性体系中,将合适的脱酰基酶以溶解或固体形式加入到生物质的悬浮液中,形成相应的核,并且任选分离和纯化核, 其中通过发酵获得的脂肽在发酵结束后作为细胞结合的生物质反应,直接用脱酰基酶进一步纯化,由此消除通过酰胺键连接的N-酰基链。
