Strain Engineering for Adipic Acid

Online Inquiry

CD Biosynsis uses renewable resources to synthesize adipic acid through metabolic engineering and optimization of fermentation conditions and is committed to exploring ways to increase the yield of adipic acid.


Adipic acid is an aliphatic dicarboxylic acid containing 6 carbons. Adipic acid is naturally found mainly in human urine, and its presence in plants and microorganisms has not been reported. Adipic acid has been widely used as a monomeric raw material for the production of polymers such as nylon, chemical fibers, and engineering plastics in the food, pharmaceutical, and plastic industries. Currently, the main production method for adipic acid is nitric acid oxidation using a mixture of cyclohexanol and cyclohexanone as raw materials. However, the strong oxidizing nitric acid in the nitric acid oxidation process causes severe corrosion of the equipment and generates nitrogen oxides as a by-product, which causes great environmental pollution. Therefore, the direct production of adipic acid using microorganisms has become a major concern for synthetic biologists.

How We Can Help

Optimization of Adipic Acid Synthesis Pathway

Microorganisms can synthesize adipic acid directly from a variety of edible raw materials. We can provide a variety of metabolic engineering modification strategies to help our customers improve the efficiency of adipic acid production. We are able to provide optimization services for the following adipic acid synthesis pathways.

  • Optimization of the ω-oxidation pathway. We can optimize the three stages of the ω-oxidation pathway using a module optimization strategy. We improve the yield of adipic acid by regulating the expression levels of genes related to the hydroxylation and oxidation modules, respectively.
  • Optimizing the β-oxidation pathway. We can overexpress key genes in the β-oxidation pathway or construct cofactor regeneration systems to increase the yield of glycolic acid.

Construction of a Novel Synthetic Pathway for Adipic Acid

Adipic acid can be degraded to succinyl coenzyme A and acetyl coenzyme A in microorganisms, and our scientists are working to design the inverse adipic acid degradation pathway to achieve the synthesis of glycolic acid. If you would like to join us in exploring synthetic pathways for inverse adipic acid degradation in microorganisms, please contact us directly.

Construction of a Semi-Synthetic Pathway for Adipic Acid

We have successfully constructed a semi-synthetic pathway for the production of adipic acid from glucose. We use microbial fermentation to produce glucaric acid and then prepared adipic acid chemically using the monopotassium salt of glucaric acid as the starting reactant.
