The invention relates to a method for producing organic compositions comprising the method steps: A) providing an oxyhydrogen bacterium having an activity of an enzyme E 1 , which is increased by comparison with the wild type thereof and which can catalyse the conversion of 2 acetyl-CoA to acetoacetyl-CoA and CoA, in an aqueous medium; B) bringing the aqueous medium into contact with a gas containing H 2 , CO 2 and O 2 in a weight ratio from 20 - 70 to 10 - 45 to 5 - 35 and optionally C) purifying the organic composition. |
