Bioelectrochemical vs hydrogenophilic approach for CO2 reduction into methane and acetate
Methane and acetate production through CO2 reduction has been tested by using chemoautotrophic microorganisms under bioelectrochemical and hydrogenophilic conditions. For the methanogenic tests, a thermophilic anaerobic sludge has been used as inoculum while the thermal treatment of the anaerobic sludge allowed the acetogenic inoculum selection.
