CD Biosynsis has established a powerful synthetic biology platform for improving the economic production of glutamic acid and its derivatives and leading the way to sustainable manufacturing. Our experienced scientists can help our customers develop efficient strategies for glutamic acid-producing microorganism improvement and process optimization to meet the growing global demand for glutamic acid.
Advantages of Synthetic Biology-Driven Glutamic Acid Production
Glutamic acid with the molecular formula C5H9NO4 is a nonessential amino acid found in animal and plant proteins. Its ionic form, known as glutamate, plays a critical role in neural activation as a neurotransmitter. The glutamic acid market has been growing and continues to expand due to the wide range of applications of glutamic acid and its derivatives in various industries such as food and pharmaceuticals. Traditional fermentation process can be affected by many factors such as permeability, substrate concentration, carbon source, nitrogen source, medium pH, temperature, growth factors, and oxygen supply. Synthetic biology approaches based on engineering concepts allow the construction of microbial cell factories under precise control to reprogram cellular properties and provide access to novel low-cost carbon sources. The rapid development of synthetic biology has opened up new avenues for improving the microbial production of glutamic acid and its derivatives.

How We Can Help
CD Biosynsis has been exploring microbial metabolic pathway for glutamic acid production and focused on the biosynthetic mechanism. We have the ability to use synthetic biology techniques to improve productivities of glutamic acid-producing microorganisms or to design and create innovative metabolic pathways to improve the yield and efficiency of the biosynthetic processes. By construction of synthetic biology-powered microbial cell factories for efficient production of glutamic acid and its derivatives, we are committed to meeting our customers' needs in an environmentally sustainable and cost-effective way.
Synthetic Biology-Driven Production of Glutamic Acid/Glutamate
We have developed powerful synthetic biology toolboxes for different species of microorganisms, including but not limited to omics tools, computational tools, genome-wide editing tools, synthetic regulatory tools for microbial engineering, and metabolite biosensors. We have expertise and experience to develop effective strategies for engineering of glutamic acid-producing microorganisms to increase productivity and yields. We can also help isolate and characterize novel microbial strains with ability to secrete high concentration of glutamic acid and tolerance to high glutamic acid concentration. The following is a collection of glutamic acid-producing microorganisms.

Synthetic Biology-Driven Production of Poly-γ-Glutamic Acid
Poly-γ-glutamic acid (γ-PGA) is a natural occurring biodegradable biopolymer made up of D/L-glutamic acids. We can help develop synthetic biology strategies for improving γ-PGA production including modifying microbial biosynthetic pathways, enhancing the production of glutamic acid as the precursor for γ-PGA synthesis, and decreasing competitive byproduct production. The microorganisms that have the potential to be developed as synthetic biology chassis for γ-PGA production are listed below. We are also working to discover microorganisms capable of vigorous γ-PGA biosynthesis from renewable feedstocks to help our customers develop sustainable production processes and reduce costs.
