Comparison of identified bacterial metabolites in 48-h culture broths of Xenorhabdus nematophila (Xn) and Photorhabdus temperata subsp. temperata (Ptt). Abbreviations: BZA, benzylideneacetone; Ac-FGV, acetylated FGV tripeptide; PY, PY dipeptide; cis-cPY, cis-cyclo-PY; indole, 1H-benzo[b]pyrrole; oxindole, 2-indolinone; PHPP, p-hydroxyphenyl propionic acid. (A) Reverse-phase HPLC chromatograms of ethyl acetate extracts of the bacterial culture broths. (B) Measurements of seven bacterial metabolites in the bacterial culture broth. Each measurement was independently estimated three times. Means followed by different letters indicate significant differences among means at a type I error of 0.05 (LSD test).
