Steady state results of maltose-limited chemostat cultures. Mean values ± standard deviations are given for N402 and B36 from triplicate independent steady-state cultures. Bold letters indicate significant differences based on a two tailed t-test (p < 0.001). Cbiomass, dry weight of biomass concentration; Yx/s and Yx/c, growth yield on substrate and carbon; qCO2 and qO2, specific carbon dioxide evolution rate and oxygen consumption rate; RQ, respiratory quotient; qprotein-EC, specific extracellular protein production rate; C-recovery, carbon recovery.
