  1. Culture condition A: 8 g/L HCOONa, 1 g/L yeast powder, 0.5 g/L NaCl, 0.5 g/L MgCl2.6H2O, 0.1 g/L CaCl2.2H2O, 0.5 g/L KCl, 0.2 g/L KH2PO4. Culture condition B: 20 g/L HCOONa, 1 g/L yeast powder, 0.5 g/L NaCl, 0.5 g/L MgCl2.6H2O, 0.1 g/L CaCl2.2H2O, 0.5 g/L KCl, 0.2 g/L KH2PO4. Culture condition C: 8 g/L HCOONa, 2 g/L (NH4)2SO4, 0.5 g/L NaCl, 0.5 g/L MgCl2.6H2O, 0.1 g/L CaCl2.2H2O, 0.5 g/L KCl, 0.2 g/L KH2PO4. Error bars ( ±) represent the standard deviation of three replicates. Letters indicate statistically significant differences, as determined by Student’s t test (aindicates p < 0.01; bindicates no significance)
