Fatty acid and derivatives production

摘要

The present invention relates to at least one method of producing at least one fatty acid and/or derivative thereof from a gas comprising H 2 , CO 2 and O 2 the method comprising the steps of:
(c) providing a genetically modified hydrogen oxidising bacterium in an aqueous medium; and
(d) contacting the aqueous medium with a gas comprising H 2 , CO 2 and O 2 in a weight ratio of 20 to 70: 10 to 45: 5 to 35;
wherein the fatty acid comprises at least 5 carbon atoms and
wherein the hydrogen oxidising bacterium is genetically modified relative to the wild type bacterium to increase the expression of enzyme E 1 that is capable of catalysing the conversion of acetyl CoA to acyl ACP via malonyl coA and to increase the expression of enzyme E 2 that is capable of catalysing the conversion of Acyl ACP to the fatty acid.
