Fig. 4From: Xenorhabdus khoisanae SB10 produces Lys-rich PAX lipopeptides and a Xenocoumacin in its antimicrobial complexThe UPLC profiles of fraction B collected from C18-HPLC (refer to Fig. 2 b). The top chromatogram (a) shows the base peak intensity mass chromatogram of fraction B and the middle chromatogram (b) the mass extracted chromatogram for the molecular ion with m/z 407.217 at 30 ppm tolerance. The bottom chromatogram (c) shows the spectrophotometric profile at 314 nm and the insert shows the UV spectrum of the peak at 4.23 minBack to article page
