Gotoh. Electronic supplementary material Additional file 1: Figure S1. Cross-streak experiment for detection of bacterial interaction via acyl-HSLs. The two monitor strains used were KG7004 (ΔlasI ΔrhlI) and KG7050 (ΔlasIΔrhlI4 ΔmexB) harboring the lasB promoter-gfp plasmid (pMQG003) were used. Test strains against the monitor strains (center) were cross-streaked on LB agar plates. Following 24 h incubation at30°C, the growth of strains was observed under a stereomicroscope, and then production of GFP by the monitor strains was visualized by excitation of the plates with blue light.

Extracted samples from V. anguillarum CP673451 order cultures were chromatographed GSK2126458 research buy on a C-18 RP-TLC plate, developed with methanol/water (70:30, v/v). The spots were visualized 13 by overlaying the TLC plate with C. violaceum VIR07. As AHL standards, Cn-HSL: 14 C6-HSL, C8-HSL and C10-HSL, 3-oxo-Cn-HSL: 3-oxo-C6-HSL, 3-oxo-C8-HSL, 15 3-oxo-C10-HSL and 3-oxo-C12-HSL were used.
