Figure 1. Imaging mass spectrometry and molecular networking analysis of Vibrio sp.
QWI-06 and structures of vitroprocines A-J (1–10). Three clusters in molecular networking of Vibrio sp. QWI-06 extract consist of seven subgroups (A–G). Six nodes were observed in the imaging mass spectrometry of Vibrio sp. QWI-06 colony grown on marine agar medium including subgroup A: m/z 320 (1) and 348 (2); subgroup B: m/z 322 (3); subgroup C: m/z 364 (5); subgroup D: m/z 304 (8); and subgroup F: m/z 292. m/z 715 is polyglutamate analogue commonly found in bacteria. Eight nodes (shown is green hexagon) were isolated in this study: 1–6, 8 and 10.
