Bacteria and method for synthesizing fatty acids

摘要

There is provided a recombinant bacterium comprising at least one overexpressed acyl-ACP thioesterase gene, and wherein at least one gene from the tricarboxylic acid cycle or glycolysis or both is inactivated. There is also provided a method for producing fatty acids, said method comprising culturing bacteria comprising at least one overexpressed acyl-ACP thioesterase gene in a growth medium in a container having walls; allowing said bacteria to secrete fatty acids; and collecting said fatty acids. Acid supplementation is also shown to increase productivity.
