Genotype | Wild type |
Culture medium | A minimal medium consisting of 10 g glucose per liter, 48 mM Na2HPO4, 22 mM KH2PO4, 10 mM NaCl, and 40 mM (NH4)SO4, was used. For minimal medium, the following components were filter-sterilized separately and then added (per liter of final volume): 1 ml 1 M MgSO4, 1 ml 0.1 mM CaCl2, 1 ml vitamin B1 (1 mg/l stock) and 10 ml trace element solution containing (per liter): 0.55 g CaCl2, 1 g FeCl3, 0.1 g MnCl2-4H2O, 0.17 g ZnCl2, 0.043 g CuCl2-2H2O, 0.06 g CoCl2-2H2O, and 0.06 g Na2MoO4-2H2O. |
