Strain Engineering for Succinic Acid

CD Biosynsis is committed to helping customers achieve high succinic acid production at low pH by building more robust microbial hosts or developing low-cost feedstock-based fermentation processes.

Advantages of Synthetic Biology-Driven Succinic Acid Production

Succinic acid is an intermediate product of the tricarboxylic acid cycle as well as a fermentation product of anaerobic metabolism. Succinic acid is widely found in humans, animals, plants, and microorganisms, and is a highly promising C4 platform chemical that has been widely used in food, chemical, pharmaceutical, surfactant, biodegradable plastic, and other fields. Traditional production of succinic acid uses petroleum as raw material, which has the disadvantages of high prices and high pollution. Due to the depletion of fossil fuels and environmental concerns, the biosynthesis of succinic acid has received increasing attention. The main source of raw material for succinic acid biosynthesis is maize, which not only provides the carbohydrates necessary for the growth of the bacterium but also provides a cheap source of carbon. The production of succinic acid by synthetic biology method has the advantages of low raw material cost and environmental friendliness.

How We Can Help

Strain Improvement

We are able to apply genetic engineering tools to modify existing strains for succinic acid production. We expect to work with our customers to solve the problems of low succinic acid production capacity of natural strains, variety of fermentation products, and poor tolerance of strains to sugar or succinic acid. We are able to develop high succinic acid-producing strains through targeted mutations, genetic modifications, genome editing, and other technologies. For example, the overexpression of genes that promote succinic acid production, and the development of strains that can utilize amino acids to produce succinic acid. The following table shows the strains for which we can provide succinic acid biosynthesis development services. If the strain you are interested in is not on the table, please contact us directly.

Metabolic Evolution of Pathways for High-Yield Succinic Acid Production

Metabolic evolution refers to the metabolic rearrangement of imbalances compensated by the adaptation of the organism. We are able to help our customers activate the pentose phosphate pathway and transhydrogenase activity to increase succinate production in microbial strains.

Fermentation Process Improvement

We are able to help our customers optimize the batch fermentation process, the make-up batch fermentation process, and the continuous fermentation process involved in the production of succinic acid. Based on a precision fermentation platform, we improve the production efficiency of succinic acid strains and reduce the total cost of production.

Applications of Succinic Acid

CD Biosynsis can develop tailored tools and customized approaches to harness the power of synthetic biology to drive succinic acid production and meet the needs of customers in a variety of industries.

• Used as an ideal acidifier in food processing.
