Strain Engineering for Flavonoids

Online Inquiry

CD Biosynsis is able to use metabolic engineering and genetic engineering to alter the metabolic flow of flavonoids, expand their metabolic pathways, and construct new metabolic pathways to modify the metabolic purpose of cells to meet the specific needs of humans with flavonoid production.


Flavonoids are widely distributed in the plant world, and more than 2,000 kinds of natural flavonoids have been found. Flavonoid compounds are secondary metabolites of the flavonoid biosynthetic pathway and are highly abundant in the flowers and leaves of plants. Anthocyanins are one of the end products of flavonoid metabolism. Flavonoids have various effects such as antibacterial, anti-inflammatory, and antioxidant. The research, development, and application of flavonoids have become an important direction in the fields of food, medicine, chemical, and biological engineering. As the application of flavonoid compounds continues to expand, flavonoids produced from plant extracts are no longer able to meet the market demand due to the influence of plant growth. Therefore, the use of synthetic biology can enable the large-scale production of flavonoids.

What We Provide

With the development and maturation of proteomic, genomic, and transcriptomic analysis technologies in exploring the molecular mechanisms of plant secondary metabolism, we are able to regulate the flavonoid production process using metabolic and genetic engineering to achieve large-scale production of flavonoids without plant growth cycle limitations.

Featured Services

  • We are able to use transcription factors or regulatory genes to regulate flavonoid biosynthetic pathways.
  • We are able to modify or regulate structural genes in the flavonoid biosynthetic pathway.
  • We are able to alter the flow of flavonoid metabolic pathways, reducing or blocking the synthesis of non-target metabolites and providing more adequate synthetic precursors for the synthesis of target flavonoids.
  • We are able to produce flavonoids through plant healing tissue culture using plant tissue culture techniques.


  • Efficient cell factory for flavonoid production.
  • Flavonoids and flavonoid compounds.

How We Can Help

Development of Microbial Chassis for Flavonoid Production

Microorganisms are fast-growing, easy to culture, and suitable for large-scale fermentation production. The synthesis of flavonoids using microorganisms has high feasibility and use value. We are able to express flavonoid synthesis-related genes in microorganisms and carry out fermentation and achieve large-scale and industrial production of flavonoids through the optimization of strain selection and fermentation condition control. The following are the microbial chassis that has been used for the production of flavonoids. Please contact us directly if you have other chassis of interest for flavonoid production.

Microbial Co-Culture for Flavonoid Synthesis

Based on the well-defined molecular mechanism of the flavonoid synthesis pathway, we are able to produce flavonoids by modular co-culture of two or more microorganisms. Through the co-culture system, we divide the flavonoid synthesis pathway into different modules to provide better reaction conditions for the key enzymes in the synthesis pathway, reduce the metabolic burden of microbial strains, and improve the efficiency of flavonoid production. We are able to improve strains using physical mutagenesis, chemical mutagenesis, and conformational mutagenesis. The following table shows the co-cultivation system we have successfully built. If you would like to build other strain combinations or more than two microbial co-culture systems, you can contact us directly or fill out the online form to let us know and we will be happy to explore new co-culture systems with you.
