| 摘要 |
The invention provides a non-naturally occurring microorganism comprising one or more gene disruptions, the one or more gene disruptions occurring in genes encoding an enzyme obligatory to coupling 1,4-butanediol production to growth of the microorganism when the gene disruption reduces an activity of the enzyme, whereby the one or more gene disruptions confers stable growth-coupled production of 1,4-butanediol onto the non-naturally occurring microorganism. The microorganism can further comprise a gene encoding an enzyme in a 1,4-butanediol (BDO) biosynthetic pathway. The invention additionally relates to methods of using microorganisms to produce BDO.
