A native CO$_2$-reducing bacterium: Discovery, implementation and interests

Résumé

Stenotrophomonas maltophilia has been demonstrated herein to reduce CO$_2$ without any cofactor, photon or hydrogen (H$_2$) addition during reaction. S. maltophilia reduces $^{13}$CO$_2$ into $^{13}$C-labeled formate in batch mode. Two intracellular enzymes are curently being considered for their ability to catalyze the CO2 reduction reaction: a Fe-nitrogenase and a formate dehydrogenase (FeS-FDH). The reaction was intensified by implementing the bacteria in an electrolysis cell continuously fed with CO$_2$ In this configuration, CO$_2$ removal reached up to 25% v/v at 30°C and atmospheric pressure
