  • Publication number: 20200224233
    Abstract: A method for producing ectoine by fermenting recombinant Corynebacterium glutamicum. The recombinant Corynebacterium glutamicum is obtained by overexpressing, in Corynebacterium glutamicum, 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 recombinant Corynebacterium glutamicum can 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 recombinant Corynebacterium glutamicum solves the biosafety problem, simplifies the post-extraction process, and has a good market application prospect.
