Malonic acid is currently a high-value specialty chemical useful for production of a variety of pharmaceuticals, flavors, fragrances, and specialty materials. Source
The petrochemical process to produce malonic acid requires chloroacetic acid and sodium cyanide, and is both costly and environmentally hazardous. Lygos’ fermentation technology is environmentally benign, scalable, and enables production of malonic acid at a lower cost than the current petrochemical manufacturing process. Source
