Abstract
The invention discloses a method for producing glutaric acid by whole-cell biocatalysis. The method firstly induces expression and collects recombinant strainsE.coliBL‑22AB‑YDTCells of (2) andE.coli28LGOXthe recombinant strain is culturedE.coli28LGOXCells and recombinant bacteria ofE.coliBL‑22AB‑YDTThe cells of (a) are as follows 1: 1-5, adding substrates L-lysine and L-glutamic acid after mixing, and enabling the molar ratio of the L-glutamic acid to the L-lysine to be 1: 0.5-4, adding a surfactant, and producing glutaric acid by whole-cell catalysis. The method of the invention does not need to add 2-ketoglutaric acid, reduces the production cost, solves the problems of long production period, complex metabolite, low substrate conversion rate, difficult product separation and extraction and high energy consumption of a fermentation method, also solves the defect that the cascade catalysis process in the enzyme catalysis is not easy to realize, improves the catalysis efficiency, and saves the enzyme purification process.
Description
Technical field
The present invention relates to field of biotechnology, and in particular to a kind of method of Whole Cell Biocatalysis production glutaric acid.
Background technique
Glutaric acid, alias: glue acid, a, γ-propane dicarboxylic acids, 1,3- propane dicarboxylic acid, can be used as important industrial chemicals and
Organic intermediate has a wide range of applications in all fields.In the industry, glutaric acid can be used for synthesizing polyvinyl chloride, polyester, gather
In addition amide and the polyester plasticizer of polyvinyl chloride etc. can be used for synthesizing liquid polyester (the molecule knot of improvement PET fiber
Structure improves the dyeability of PET fiber, improves dye-uptake).In terms of medicine, glutaric acid can be used for synthesizing various sterilizings and wash
Liquid and drug, in addition, glutaric acid can be used for the ingredients of detergent, the flue gases such as the preparation of adhesive and sulfur-bearing in life
Washing etc..
At present in the method for synthesizing glutaric acid, there is chemical synthesis, such as using gamma-butyrolacton as the multi-step synthetic method of raw material,
Using cyclopentanol-cyclopentanone as the choice oxidation process of raw material, hydrolysis is aoxidized by raw material of dihydrofuran, by malonate two
Prepared in the presence of second ammonium with formaldehyde condensation etc..But this method raw material is costly, is not easy to obtain and major part has used strong oxidizer, it is right
The corrosion of equipment is very big.React complex, there are many reaction step, and yield is not high, and environmental pollution is more serious, are only limited to test
Room, industrial prospect are little.
