ABSTRACT
A lipopeptide compound was isolated from the culture of Bacillus subtilis HSO121 by methods of acidic precipitation, solvent extract, fractional precipitation, adsorption and prepared thin-layer chromatography; and its molecular structure was determined by by ninhydrin assay and IR methods following the Amino analysis, MS-MS and ESI-MS. It shows that the isolated lipopeptide consists of two homologues with molecular mass 1,022D and 1,036D and bearing a cyclic structure with the amino acid sequence Leu-Leu-Asp-Val-Leu-Leu-Glu in the peptide chain, which indicates that the isolated lipopeptide falls into the analogs of surfactin.
