Deep Conversion of Carbon Monoxide to Hydrogen and Formation of Acetate by the Anaerobic Thermophile Carboxydothermus hydrogenoformans

Figure 1

Final CO levels of the hydrogenogenic CO metabolism of C. hydrogenoformans was studied batch cultures, with CO₂ trap and without CO₂ trap (open versus closed symbols, resp.), in triplicate. Optical density of cultures ((a), square symbols), and partial pressures of CO ((b), triangles), H₂ (diamonds), and CO₂ (circles) were monitored over time and plotted on a linear axis. Trace levels of CO (c) were plotted on a logarithmic axis from 15.5 h onward.
