Synthesized Adipic Acid for Renewable Chemical Production 2015-106

Researchers at the Joint BioEnergy Institute (JBEI) have developed a technology utilizing polyketide synthases (PKS) for biologically synthesizing a dicarboxylic acid. These diacids, such as adipic acid, are the starting materials required for the synthesis of nylons and polyester products. Rather than relying on acid extraction from petroleum and other fossil fuels, this method uses renewable sugar feedstocks yielding a sustainable method of polyester synthesis. Other laboratories have modified the same type of enzymes for the manufacture of pharmaceutical and agricultural products, but the JBEI team is the first to design PKSs to synthesize dicarboxylic acids. PKSs are enzymes that produce compounds that possess antibacterial, immunosuppressive, and anti-cancer qualities. Through the manipulation of PKS reactions that utilize sugar as an energy source, the process of creating diacid derivatives to be used in polyester synthesis becomes streamlined and renewable. The sugars can be derived from the deconstruction of biomass. Currently, millions of metric tons of fossil fuels are used for commodity chemical production.
