Described are hosts for overproducing a fatty acid product such as a fatty acid. The hosts include an exogenous nucleic acid encoding a thioesterase and, optionally, an exogenous nucleic acid encoding an acetyl-CoA carboxylase, wherein an acyl-CoA synthetase in the hosts are functionally deleted. The hosts preferably include the nucleic acid encoding the thioesterase at an intermediate copy number. The hosts are preferably recombinantly stable and growth-competent at 37° C. Methods of producing a fatty acid product comprising culturing such hosts at 37° C. are also described. |
