Strain Engineering for Valine

Online Inquiry

CD Biosynsis is dedicated to solving problems in valine biosynthesis and improving the production efficiency and conversion rate of valine so as to achieve large-scale production of valine.


Valine is one of the three branched-chain amino acids and an essential amino acid for human beings. Valine has various physiological functions and plays an irreplaceable role in various physiological activities of living organisms. Valine is widely used in medicine, food additives, feed additives, and other fields. Currently, valine is produced by extraction, synthesis, and fermentation methods. However, the extraction method and chemical synthesis method are costly and the reaction is complicated, which is not suitable for industrial production. Therefore, it is important to develop synthetic biology methods for the large-scale production of valine.

How We Can Help

Development of Microbial Chassis for Valine Production

We can help our customers develop microbial strains for the efficient production of valine. Our scientists are able to select high-yielding mutant strains based on biosynthetic pathways. We have achieved the synthesis of valine with the strains in the following table. Please contact us directly if you have other chassis of interest for valine production.

Corynebacterium glutamicum Escherichia coli Bacillus subtilis Saccharomyces cerevisiae Bacillus licheniformis

Optimization of Fermentation Conditions

Oxygen supply, different carbon and nitrogen sources, and biotin concentration can affect the yield of valine. We can ensure a significant increase in microbial growth and fermentation product yield by optimizing the fermentation conditions parameters.

Selection and Breeding of Valine High-Yielding Bacteria

We can select and breed leucine and isoleucine nutrient-deficient mutant strains or anti-feedback-regulated mutant strains to increase valine production by changing the metabolic pathway and increasing precursor substance synthesis.
