CD Biosynsis provides our customers with powerful synthetic biology capabilities to help them overcome challenges in the biotechnological production of propionic acid (PA) and meet the market demand for sustainable production. Our scientists have established a state-of-the-art synthetic biology platform to enable improved PA production in engineered microorganisms. We are committed to promoting the production of bio-based propionic acid as a more sustainable approach to meet the growing market demand.
Propionic acid with the molecular formula C3H6O2 is a valuable C3 platform chemical with a wide range of applications in several industries including food, agriculture, chemical, and pharmaceutical industries. Although biotechnological production of PA cannot economically compete petrochemical routes, these bio-based methods has attracted continued interest in light of growing concerns about petroleum shortage and environmental pollution. However, the bio-based propionic acid production process still faces many difficulties, such as low yield, poor productivity, strong end-product inhibition, and challenges in engineering propionibacteria. Recent progress in synthetic biology provides new tools and strategies for the development of engineered microorganisms with improved fermentation capabilities and improved tolerance to PA. Synthetic biology may contribute greatly to advance the green and economical biotechnological production of PA.

Leveraging our powerful synthetic biology platform, CD Biosynsis can provide our customers with custom synthetic biology services to help them develop effective strategies to achieve efficient biosynthesis of propionic acid.
CD Biosynsis has established a multidisciplinary team with expertise in synthetic biology, systems biology, and industrial fermentation technologies to help our customers overcome challenges and tackles in microbial engineering, improve PA production and optimize fermentation processes.
Engineering of Microbial Chassis for Propionic Acid Production
We can assist our customers with the design, engineering, and modification of microbial chassis to improve their PA productivity and acid tolerance using a wide range of genetic and metabolic engineering techniques. We focus on the study of microbial biosynthetic pathways of PA and have the ability to develop pathway engineering strategies to increase metabolic flux towards PA biosynthesis, increase yields and productivity, and decrease by-products.

Fermentation Process Optimization
PA produced through anaerobic fermentation faces a number of challenges such as slow growth rates and product inhibition. We can develop strategies to generate engineered microorganisms with enhanced resistance to end-product inhibition, explore inexpensive renewable carbon sources for PA production, and optimize fermentation conditions. Our experience in the successful scale-up of fermentation processes can support the increasing demand for industrial PA production.
CD Biosynsis can provide our customers with advanced synthetic biology tools and strategies to help our customers higher yield and productivity of PA to meet the growing demand in different industries.
As a rapidly growing synthetic biology company, CD Biosynsis is committed to helping our customers meet the growing and evolving demand for bio-based chemical production. All of our deliverables will undergo a rigorous quality testing process to ensure the quality and reliability and can be delivered on time.
