摘要

The apparent solubility and bioavailability of hydrophobic compounds, the main problems in the bioremediation process, can be overcome by bacteria producing biosurfactants. Lipopeptide biosurfactants, as high-efficiency biosurfactants with biological activity, can be synthesized by nonribosomal peptide synthetase (NRPS). In this study, two strains, Paenibacillus lautus A (HC_A) and Lysinibacillus fusiformis B (HC_B), which can efficiently produce lipopeptide biosurfactants, were screened. The NRPS gene sequences of these two strains were obtained by whole-genome sequencing. The module of synthetic surfactant NRPS from HC_A and the module of synthetic surfactants NRPS and sfp from HC_B were successfully cloned i... More
