[Isolation and identification of lipopeptides produced by Bacillus subtilis fmbJ].
Isolation and idenfication of lipopeptides from Bacillus subtilis fmbJ was carried out in this paper. With HPLC method, it was determined that the antimicrobial substance was composed of many components, and one of them had the similar retention time similar to surfactin. In addition, the antimicrobial substance was proved to include the closed cycle peptide bind by TLC, and one of them had the migrating rate similar to surfactin. Furthermore, ESI-MS analysis showed that the antimicrobial substance contained five homologues of fengycin, such as m/z1449.9, m/zl1463.8, m/zl1477.8, m/z1491.9 and m/z1505.9, and three homologues of surfactin, such as m/z1008.8, m/z1022.8 and m/z1036.8.
