Homologous production, one-step purification, and proof of Na⁺ transport by the Rnf complex from Acetobacterium woodii, a model for acetogenic conversion of C1 substrates to biofuels.

ABSTRACT:

Background

Capture and storage of the energy carrier hydrogen as well as of the greenhouse gas carbon dioxide are two major problems that mankind faces currently. Chemical catalysts have been developed, but only recently a group of anaerobic bacteria that convert hydrogen and carbon dioxide to acetate, formate, or biofuels such as ethanol has come into focus, the acetogenic bacteria. These biocatalysts produce the liquid organic hydrogen carrier formic acid from H₂ + CO₂ or even carbon monoxide with highest rates ever reported. The autotrophic, hydrogen-oxidizing, and CO₂-reducing acetogens have in common a specialized metabolism to catalyze CO₂ reduction, the Wood-Ljungdahl pathway (WLP). The WLP does not yield net ATP, but is hooked up
