Medium composition

Synthetic medium: 48mM Na2HPO4, 22mM KH2PO4, 10mM NaCl, 45mM (NH4)2SO4, 4g/L glucose, 1mM MgSO4, 1mg/L thiamin.HCL, 5.6 mg/L CaCl2, 8 mg/L FeCl3, 1 mg/L MnCl2.4H2O, 1.7 mg/L ZnCl2, 0.43 mg/L CuCl2.2H2O, 0.6 mg/L CoCl2.2H2O and 0.6 mg/L Na2MoO4.2H2O

General protocol information Sampling method: Aliquots of 10 mL were withdrawn at OD600 0.85

Quenching procedure: Cells were filter (0.45-µm), washed with 10 mL of Milli-Q water and plunged into 1 mL of methanol containing 10µL of 0.56 mM PIPES

Extraction technique: chloroform

Sample analyzing method: CE-MS

Methods description - Notes

Metabolites were quantified using peak areas obtained from measurements of chemical standards mixtures that were analyzed in parallel with experimental samples. See more details in the original article.
