Publication number: 20240043884Abstract: The present invention provides recombinant Escherichia coli for producing glutarate, a construction method and use thereof. A double-plasmid recombinant bacterium is constructed through molecular biological means for co-expressing an aldehyde synthase (AAS) gene, an amine oxidase Mao (gene) and an aldehyde dehydrogenase (Glox) gene. The constructed expression plasmids are introduced into the Escherichia coli to reconstruct to obtain recombinant cells. A recombination strain for efficiently producing glutarate is obtained through amicillin resistance and kanamycin resistance combined plate screening. Efficient production of the glutarate is achieved by optimizing concentration of a substrate, cell concentration and a transformation temperature. L-lysine with a concentration of 30 g/L may be transformed into 19.Type: ApplicationFiled: December 3, 2021Publication date: February 8, 2024Inventors: Liming LIU, Zhilan ZHANG, Cong GAO, Xiulai CHEN, Liang GUO, Jia LIU, Wei SONG
