NOVELTY - A recombinant photoautotroph microorganism (G1) that produces an alcohol selected from 1-propanol, isobutanol, 1-butanol, 2-methyl-1-butanol, 3-methyl-1-butanol and 2-phenylethanol from carbon dioxide as the carbon source, is new. The alcohol is produced from a metabolite comprising 2-keto acid.    USE - For producing an alcohol selected from 1-propanol, isobutanol, 1-butanol, 2-methyl-1-butanol, 3-methyl-1-butanol, or 2-phenylethanol, from carbon dioxide as the carbon source, via a metabolite comprising 2-keto acid (claimed), the alcohols are useful as biofuels or alternative energy source.    ADVANTAGE - The recombinant photoautotroph microorganism has elevated expression or activity of: acetohydroxy acid synthase, acetohydroxy acid isomeroreductase, dihydroxy-acid dehydratase, 2-keto-acid decarboxylase, and alcohol dehydrogenase; or elevated expression or activity of: acetolactate synthase, acetohydroxy acid isomeroreductase, dihydroxy-acid dehydratase, 2-keto-acid decarboxylase, and alcohol dehydrogenase; as compared to a parental microorganism, for producing isobutanol from CO2 as the carbon source.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) a culture for the production of an alcohol selected from 1-propanol, isobutanol, 1-butanol, 2-methyl-1-butanol, 3-methyl-1-butanol and 2-phenylethanol from carbon dioxide as the carbon source, where the alcohol is produced from a metabolite comprising 2-keto acid, the culture comprising a first microorganism comprising a wild-type or recombinant photoautotroph or photoheterotroph and a second microorganism comprising a recombinant microorganism capable of converting a 2-keto acid to the alcohol;    (2) producing the recombinant photoautotroph microorganism (G1); and    (3) producing an alcohol involving: (a) providing a recombinant photoautotroph microorganism (G1) or a culture comprising a photoautotroph and a recombinant microorganism, (b) culturing the microorganisms of (a) in the presence of CO2 under conditions suitable for the conversion of the substrate to an alcohol, and (c) detecting the production of the alcohol.
