From: From formic acid to single-cell protein: genome-scale revealing the metabolic network of Paracoccus communis MA5

Sample Formic acid absorption (g/L) Biomass (OD600) Protein content (%)
A 4.61 ± 0.24 0.56 ± 0.07 44 ± 1.55
B 1.51 ± 0.22 a 0.49 ± 0.09b 30 ± 1.79a
C 4.40 ± 0.37 b 0.21 ± 0.05a 53 ± 1.31a
  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)
