Sampleprep Summary:Sample metabolite extraction A volume of 1 mL of the extraction solvent (methanol+0.1% formic acid) was added to the cell pellets to quench cells. The cells were then vortexed for 2 min to ensure the quantitative extraction of the metabolites and stored on ice for 1 h, during which the samples were vortexed every 15 min. After this, the insoluble cell matrices were collected and transferred to centrifuge tubes, intermittent ultrasonication using the COPLEY sonicator (QSONICA SONICATOR, USA) under 30% amplifier and for 30 s with an ice bath employed throughout the process. Following that, cells debris were then centrifuged (15,000 rpm, 10 min, − 4 °C) and the sample supernatants were collected and transferred to LC vials for drying in the EZ-2 Plus (GeneVac-Ipswich, UK) at 37±1 °C. Dried samples were resuspended with 200 µL (water+0.1% formic acid), and vortexed for 2 min. Finally, the samples were filtered using a hydrophilic Nylon Syringe Filter of 0.45 µm pore size and analyzed by Q-TOF MS
