Growth Condition
Strains Escherichia coli K12
Genotype Wild type
Culture medium The Luria-Bertani (LB) medium contained 30% (v/v)glycerol.The precultivation medium contained 630mL fermentation medium: 8g/L glucose, 5g/L (NH4)2SO4, 3g/L KH2PO4, 1g/L NaCl, 0.3g/L MgSO4-2H2O, 0.112g/L FeSO4-7H2O, 0.75g/L thiamine, 0.15g/L 3,4-dihydroxybenzoate, 0.015g/L CaCl2-2H2O and trace elements: 0.75mg/L AlCl3-6H2O, 0.6mg/ CoCl2-6H2O, 2.5mg/L CuSO4-5H2O, 0.5mg/L H3BO3, 17.1mg/L MnSO4-1H2O, 3mg/L NaMoO4-2H2O, 1.7mg/L NiCl2-6H2O, 15mg/L ZnSO4-7H2O. The same medium was used for the precultures with the following change: 6g/L glucose.Fermentation was performed at 37 Celsius, pH 7, dissolvedoxygen (DO) 30% and a mixture of NH4/KOH was used for pH control. After glucose dropped to 1g/L,a glucose feed (60%, w/w) was started to maintain glucose concentration between 1 and 2g/L.
