US firm Verdezyne has successfully realized a proof of concept in its development project by demonstrating manufacture and recovery of adipic acid generated by a yeast microorganism from an alkane feedstock. This marks the company's first milestone towards demonstrating a 100% feedstock-flexible fermentation method for adipic acid production. Adipic acid is a key starting material for polyamides and polyurethanes production. Verdezyne's adipic acid production route has at least 20% cost advantage compared with conventional petroleum-based route.
