Mass spectra of the AHLs extracted from the cell-free supernatants of Alicycliphilus sp. B1 (A) and E. coli DH5α harboring pGEM-B1luxI (B) and a N-(3-oxodecanoyl)-l-homoserine lactone (3-OH-C10-HSL) standard (C). After fractionation of the cell-free extracts by reverse-phase HPLC, the (ESI-MS/MS fragment peaks of the AHLs were analyzed. All peaks of 3-OH-C10-HSL (m/z 272) along with the product ion peaks (m/z 102) are marked with arrows.
