Abstract EN
Carboxydothermus hydrogenoformans is a thermophilic strictly anaerobic bacterium that catalyses the water gas shift reaction, the conversion of carbon monoxide with water to molecular hydrogen and carbon dioxide.
The thermodynamically favorable growth temperature, compared to existing industrial catalytic processes, makes this organism an interesting alternative for production of cheap hydrogen gas suitable to fuel CO-sensitive fuel cells in a future hydrogen economy, provided sufficiently low levels of CO are reached.
Here we study CO conversion and final CO levels in cultures of C.
hydrogenoformans grown in batch cultures that were started with a 100% CO gas phase with and without removal of formed CO2.
Final CO levels were 117 ppm without CO2 removal and below 2 ppm with CO2 removal.
The Gibbs free energy change calculated with measured end concentrations and the detection of acetate suggest that C.
hydrogenoformans shifted from a hydrogenogenic to an acetogenic metabolism.
