Abstract

The present invention provides recombinantfor 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 theto 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 19.65 g of glutarate through reactions for 30 h under transformation conditions that the cell concentration is 30 g/L, the pH value is 8 and 6 mM of NADis additionally added, wherein a transformation rate may be 65.3%.
