title: Cyclic Lipopeptides with Herbicidal and Insecticidal Activities Produced by Bacillus clausii DTM1.
abstract: Seven cyclic lipopeptide biosurfactants (1-7) were isolated for the first time from the fermentation broth of endophytic Bacillus clausii DTM1 and were identified as anteisoC13[Val7] surfactin-(L-Glu)-O-methyl-ester (1), anteisoC12[Val7] surfactin (2), anteisoC15[Val7] surfactin (3), isoC14[Leu7] surfactin (4), anteisoC12[Leu7] surfactin (5), nC13[Leu7] surfactin (6), and anteisoC14[Leu7] surfactin-(L-Glu)-O-methyl-ester (7); 1 has not been isolated before as a natural product from any source. Plate-based herbicide and insecticide bioassays showed that all compounds exhibited interesting insecticidal and herbicidal activities.
