Abstract
A method for producing ectoine by fermenting recombinant. The recombinantis obtained by overexpressing, in, an aspartokinase gene lysC of which feedback inhibition is relieved, then replacing the promoter of the dihydrodipicolinate synthase in the recombinant bacterium to attenuate the activity of the dihydropyrimidine dicarboxylic acid synthase, and then transforming the recombinant bacterium with the ectoine synthetic path related gene ectABC. The recombinantcan be fermented using different cheap raw materials under a low salt condition to produce ectoine, and use cheap corn slurry instead of expensive yeast powder as a nutritional component, so as to further reduce the costs of the raw materials. In addition, the recombinantsolves the biosafety problem, simplifies the post-extraction process, and has a good market application prospect.
