Keywords: ppc mutant Escherichia coli, 2-Dimensional nuclear magnetic resonance, Gas chromatography-mass spectrometry, Metabolic flux analysis Full text article: no file uploaded Project name: not specified Experiment description Organism: Escherichia coli Strain: BW25113 and ppc mutant Data type: metabolites at steady-state Data units: mM Execution date: not specified Experimental details Temperature (°C): 37 pH: 7.0 Carbon source: glucose Culture mode: chemostat Process condition: aerobic Dilution rate (h⁻¹): 0.2 Working volume: 1.0 L Biomass concentration (g/L): Yield of biomass on glucose (g/g): 0,48 (WT) and 0,55 (ppc) Medium composition: M9 minimal medium as described previously [3]. General protocol information: Sampling Method: Cells were harvested by centrifugation at 10,000 g for 10 min.; Quenching: Washed twice with 100 mM Tris-HCl (pH 7.0) containing 20 mM KCl, 5 mM MnSO4, 2 mM DTT and 0.1 mM EDTA, and then resuspended in the same buffer (ca. 15 g wet cells in 50 ml buffer solution).; Extraction list: sonication; Analysis list: enzymatic; Methods description: Intracellular metabolite concentrations in quenched cell broth were measured by enzymatic procedures using a fluorescence spectrophotometer (F-4010, Hitachi Co., Japan) as described by Schaefer et al. [1] and Bergmeyer [2]. ----------------------------------References-------------------------------------- [1] Schaefer, U., Boos, W., Takors, R. and Weuster-Botz, D. (1999). Anal.
