NOVELTY - Biologically reducing carbon dioxide pollutants comprises: containing at least some carbon dioxide emissions from a carbon dioxide emitter; introducing at least some carbon dioxide emissions from the carbon dioxide emitter into at least one processing reactor; chemoautotrophically digesting carbon dioxide of the at least some carbon dioxide emissions with a set of chemoautotrophic bacteria in the processing reactor; generating reduced sulfur containing compounds from sulfate reducing bacteria in a separate processing reactor.    USE - The method is useful for biologically reducing carbon dioxide pollutants (claimed).    ADVANTAGE - The method and system can be efficiently used in capturing and converting carbon dioxide emissions from fuel consumption sources or other industrial carbon dioxide emitters.    DETAILED DESCRIPTION - Biologically reducing carbon dioxide pollutants comprises: containing at least some carbon dioxide emissions from a carbon dioxide emitter; introducing at least some carbon dioxide emissions from the carbon dioxide emitter into at least one processing reactor; chemoautotrophically digesting carbon dioxide of the at least some carbon dioxide emissions with a set of chemoautotrophic bacteria in the processing reactor; generating reduced sulfur containing compounds from sulfate reducing bacteria in a separate processing reactor; supplying the sulfur containing compounds as an energy supply to the set of chemoautotrophic bacteria in the processing reactor; biologically producing at least some biomass from the chemoautotrophic digestion of the carbon dioxide with the chemoautotrophic bacteria; ecologically reducing atmospheric release of the carbon dioxide emitted from the carbon dioxide emitter; providing an acetate conversion reactor; feeding acetate generated from the sulfate reducing bacteria into the acetate conversion reactor; and generating biomass from the acetate conversion reactor. An INDEPENDENT CLAIM is included for a processing system for biological reduction of carbon dioxide pollutants which comprises: at least one processing reactor configured to receive the at least some carbon dioxide emissions from an industrial carbon dioxide emitter; a set of chemo autotrophic bacteria in the processing reactor configured to digest at least some of the carbon dioxide; an amount of biologically produced biomass by the chemoautotrophic bacteria located in the processing reactor; an ecological reduction of atmospheric release of the carbon dioxide emissions; sulfur containing compounds generated by sulfate reducing bacteria; a supply of the sulfur containing compounds to the chemoautotrophic bacteria located in the processing reactor; an acetate conversion reactor; acetate generated from the sulfate reducing bacteria; a feed supply of the acetate from the sulfate reducing bacteria to the acetate conversion reactor; and biomass generated from the acetate conversion reactor.
