Strain Engineering for Cadaverine

CD Biosynsis is committed to using synthetic biology techniques based on genetic engineering, metabolic engineering, and protein engineering strategies to create environmentally friendly and efficient cadaverine production chassis cells for a wide range of cadaverine applications in multiple fields.


Cadaverine is a physiologically active nitrogenous base widely found in living organisms and is produced by the decarboxylation of lysine in the presence of decarboxylase during protein decay. Cadaverine is an important monomer for a variety of high-value-added products and is widely used in automotive, sporting goods, plastics, electronics, and other fields. Petroleum is the main raw material for cadaverine production. However, the increasing scarcity of petroleum resources and the multiple problems of chemical synthesis of cadaverine make it urgent to develop a method for the efficient production of cadaverine from renewable resources.

What We Provide

Based on a synthetic biology platform, our scientists combine systems biology analysis with genetic engineering, metabolic engineering and protein engineering technologies to achieve the resolution and modification of the cadaverine synthesis pathway for low-carbon and efficient cadaverine biosynthesis.

Genetic Engineering

We are able to use genetic engineering tools to modify and optimize cadaverine synthesis-related components and chassis cells to advance the biological production of cadaverine.

Metabolic Engineering

We are able to improve cadaverine production strains by systemic metabolic engineering strategies such as overexpression of key genes for cadaverine synthesis, deletion of key genes for the by-product accumulation pathway, and improved supply of cofactors.

Genomics Analysis

We are able to screen for targets capable of regulating cadaverine synthesis through genomic analysis of functional elements closely related to cadaverine synthesis and degradation.

Transcriptomic Analysis

We are able to combine transcriptome analysis with metabolic engineering to improve cadaverine production by reconstructing metabolic pathways.


  • Cadaverine producing microorganisms.
  • Cadaverine.

How We Can Help

Development of Synthetic Biology Chassis for Cadaverine Production

We are able to achieve cadaverine production using glucose, galactose, starch, mannose, xylose, etc. as carbon sources. The following are the microbial chassis that have been used for the production of cadaveric amines, and we are able to provide modification services for these microbial chassis. Please contact us directly if you have other microbial chassis of interest for cadaverine production.

Corynebacterium glutamicum Bacillus methanolicus Methylosinus trichosporium Escherichia coli

Whole Cell Transformation for Cadaverine Production

We are able to construct and optimize a whole-cell catalyst for the production of cadaveric amines. We are able to optimize the substrate transport module, product transport module, cofactor transport module, and product synthesis module in the cadaverine production cell factory based on a systematic metabolic engineering strategy to improve the performance of cadaverine production cell engineering.

Optimization of Promoter Element

The appropriate promoter is important for the efficient expression of lysine decarboxylase and the improvement of cadaverine production. We have a library of promoter elements and can help our customers to screen or design and synthesize promoters that are most beneficial for cadaverine synthesis.

Mixed Culture Fermentation

We are able to help our customers build new fermentation systems that take advantage of the synergy between the two engineered bacteria to increase the yield of cadaverine.
