Medium composition

M9 medium (per liter deionized water): 0.8 g of NH4Cl, 0.5 g of NaCl, 7.5 g of Na2HPO4 · 2H2O, and 3.0 g of KH2PO4. The following components were sterilized separately and then added (per liter [final volume] of medium): 2 ml of 1 M MgSO4, 1 ml of 0.1 M CaCl2, 0.3 ml of 1 mM filter-sterilized thiamine HCl, and 10 ml of a trace element solution containing (per liter) 1 g of FeCl3 · 6H2O, 0.18 g of ZnSO4 · 7H2O, 0.12 g of CuCl2 · 2H2O, 0.12 g of MnSO4 · H2O, and 0.18 g of CoCl2 · 6H2O. Sterilized glucose was added to a final concentration of 2 or 3 g per liter.

General protocol information Flux analysis method: 13C constrained MFA

Platform: GC-MS

Methods description - Notes

Metabolic flux ratio analysis by GC-MS - Samples for gas chromatography (GC)-mass spectrometry (MS) analysis were prepared as described previously [1]. Briefly, aliquots of 13C-labeled batch cultures were withdrawn during the mid-exponential growth phase, which was defined a ...
