Whole-cell biocatalysis for hydrogen storage and syngas conversion to formate using a thermophilic acetogen.

ABSTRACT:

Background

In times of global climate change, the conversion and capturing of inorganic CO₂ have gained increased attention because of its great potential as sustainable feedstock in the production of biofuels and biochemicals. CO₂ is not only the substrate for the production of value-added chemicals in CO₂-based bioprocesses, it can also be directly hydrated to formic acid, a so-called liquid organic hydrogen carrier (LOHC), by chemical and biological catalysts. Recently, a new group of enzymes were discovered in the two acetogenic bacteria Acetobacterium woodii and Thermoanaerobacter kivui which catalyze the direct hydrogenation of CO₂ to formic acid with exceptional high rates, the hydrogen-dependent CO₂ reduct
