NOVELTY - A multistep biological and chemical process for the capture and conversion of carbon dioxide and/or other sources of inorganic carbon, into organic compounds, where one or more steps in the process utilize obligate and/or facultative chemoautotrophic microorganisms, and/or cell extracts containing enzymes from chemoautotrophic microorganisms, to fix carbon dioxide or inorganic carbon into organic compounds.    USE - The method is useful for multistep biological and chemical process for the capture and conversion of carbon dioxide and/or other sources of inorganic carbon, into organic compounds (claimed).    ADVANTAGE - The method enables the economic capture of carbon dioxide from the atmosphere or from a point source of carbon dioxide emissions for the production of liquid transportation fuel and/or other organic chemical products, which will help address greenhouse gas induced climate change and contribute to the domestic production of renewable liquid transportation fuels without any dependence upon agriculture. In the method, the electron donors used for the chemosynthetic fixation of carbon are generated by chemical or electrochemical means, or are produced from inorganic or waste sources. An additional feature of the method describes process steps for the recovery of useful chemicals produced by the carbon dioxide capture and conversion process, both from chemosynthetic reaction steps, as well as from non-biological reaction steps.    DETAILED DESCRIPTION - A multistep biological and chemical process for the capture and conversion of carbon dioxide and/or other sources of inorganic carbon, into organic compounds, where one or more steps in the process utilize obligate and/or facultative chemoautotrophic microorganisms, and/or cell extracts containing enzymes from chemoautotrophic microorganisms, to fix carbon dioxide or inorganic carbon into organic compounds where carbon dioxide gas alone or in a mixture or solution as dissolved carbon dioxide, carbonate ion, or bicarbonate ion including aqueous solutions such as sea water, or in a solid phase including but not limited to a carbonate mineral, is introduced into an environment suitable for maintaining chemoautotrophic organisms and/or chemoautotroph cell extracts, which fix the inorganic carbon into organic compounds, with the chemosynthetic carbon fixing reaction being driven by chemical and/or electrochemical energy provided by electron donors and electron acceptors that have been generated chemically or electrochemically or input from inorganic sources or waste sources that are made accessible through the process to the chemoautotrophic microorganisms in the chemosynthetic reaction step or steps.    DESCRIPTION OF DRAWING(S) - The drawing shows a general process flow diagram for multistep biological and chemical process for the capture and conversion of carbon dioxide and/or other sources of inorganic carbon, into organic compounds.
