Carlsbad, California -- Verdezyne Inc., has achieved "proof of concept" in its development of a new fermentation process for the production of bio-based adipic acid, the company said 8 Feb.
Verdezyne, a private synthetic biology company which develops processes for renewable chemicals and fuels, said the milestone was reached by demonstrating production and recovery of adipic acid by a yeast microorganism from an alkane feedstock. Using proprietary technologies, the statement said, the company is engineering a proprietary metabolic pathway that can utilise sugar, plant-based oils or alkanes.
Adipic acid is mainly used to make polyamides and polyurethanes used in products including coatings, furniture, bedding and automobile parts, Verdezyne said.
According to Verdezyne, the advantages of developing a "feedstock-flexible fermentation process" for producing adipic acid include the ability to maintain a sustainable cost advantage regardless of future energy volatility and the reduction of greenhouse-gas emissions, compared to traditional petrochemical production.
"Our estimates indicate at least a 20 percent cost of manufacturing advantage for bio-based adipic acid depending on the feedstock selected," stated William Radany, Verdezyne president and ceo. "Rising consumer interest in bio-based products combined with a sustainable cost advantage makes Verdezyne's adipic acid process a compelling proposition for future production," he added.
Verdezyne valued the global adipic acid market at about $4900 million in 2009. (RD)
