1 .- 43 . (canceled)
44 . A method for producing an organic product, comprising:
culturing a bacterial cell in growth medium comprising a carbon-containing gas, wherein the bacterial cell chemoautotrophically converts the carbon-containing gas into organic products comprising one or more of 1,3-butanediol, 1,3-butadiene, 2-butenoic acid, 3-hydroxypentanoic acid, and 3-hydroxybutyrate; and
separating the organic products from the bacterial cell.
45 . The method of claim 44 , wherein the bacterial cell is a Ralstonia or Cupriavidus cell.
46 . (canceled)
47 . The method of claim 44 , wherein the bacterial cell produces and secretes 1,3-butadiene, and wherein the bacterial cell exhibits increased expression or activity of a fatty acid hydratase enzyme relative to a wild type cell, and
wherein the method comprises separating the 1,3-butadiene from the growth medium.
48 . The method of claim 45 , wherein the bacterial cell is a Ralstonia eutropha or a Cupriavidus necator cell.
49 .- 60 . (canceled)
61 . The method of claim 44 , wherein the bacterial cell produces and secretes
3 hydroxybutyrate monomer, and wherein the method comprises separating the 3-hydroxybutyrate monomer from the growth medium.
62 . (canceled)
63 . The method of claim 44 , wherein the bacterial cell produces 3-hydroxybutyrate polymer, and wherein the 3-hydroxybutyrate polymer is extracted from the bacterial cell.
64 . The method of claim 47 , wherein the fatty acid hydratase is an oleate hydratase.
65 . The method of claim 47 , wherein the bacterial cell is a recombinant bacterial cell that produces and secretes 1,3-butadiene, and wherein the bacterial cell expresses an exogenous fatty acid hydratase.
66 . The method of claim 65 , wherein the fatty acid hydratase is an oleate hydratase.
67 . The method of claim 44 , wherein the bacterial cell produces and secretes 1,3-butanediol, and wherein the 1,3-butanediol is separated from the growth medium using one or more of steam stripping, pervaporation, reverse osmosis, solvent extraction, and/or reactive extraction.
68 . The method of claim 67 , wherein the 1,3-butanediol is separated from the growth medium using solvent extraction with cis-9-octadecen-1-ol, ethyl acetate, tributylphosphate, diethyl ether, n-butanol, dodecanol, and/or oleyl alcohol.
69 . The method of claim 67 , wherein the 1,3-butanediol is separated from the growth medium using reactive extraction, comprising reacting the 1,3-butanediol with formaldehyde to form a formal under catalysis of acid.
70 . The method of claim 67 , wherein the separated 1,3-butanediol is converted to 1,3-butadiene by dehydration.
71 . The method of claim 44 , wherein the bacterial cell produces and secretes 1,3-butanediol, and wherein the bacterial expresses an exogenous acetolactate synthase, α-acetolactate decarboxylase, and/or 2,3-butanediol dehydrogenase.
72 . The method of claim 44 , wherein the carbon-containing gas comprises carbon dioxide, carbon monoxide, syngas, producer gas, methanol, or methane.
