| Culture medium | Batch cultivation was conducted first using LB medium containing 8g/L of glucose. For continuous cultivation, the minimal synthetic medium was used. It contained 4 g of glucose per liter(filter sterilized), 48 mM Na2HPO4, 22 mM KH2PO4, 10 mM NaCl, and 30 mM (NH4)2SO4.The following components were filter sterilized and then added (per liter of final medium): 1 ml of 1 M MgSO4, 1 ml of 0.1 mM CaCl2, 1 ml of 1 mg of Vitamin B1 per liter, and 10 ml of trace element solution containing (per liter) 0.55 g of CaCl2, 1 g of FeCl3, 0.1 g of MnCl2-4H2O, 0.17 g of ZnCl2, 0.043 g of CuCl2-2H2O, 0.06 g of CoCl2-6H2O and 0.06 g Na2MoO4-2H2O. |
