| 摘要 | The present invention relates to processes for the formation of pyridinedicarboxylic acid (PDCA), in particular, 2,4-pyridinedicarboxylic acid (2,4-PDCA) and 2,5-pyridinedicarboxylic acid (2,5-PDCA), and mono- and diester derivatives thereof, from 3,4-dihydroxybenzoic acid, via a biocatalytic reaction using, for example, a protocatechuate dioxygenase such as protocatechuate 4,5-dioxygenase or protocatechuate 2,3-dioxygenase, and a nitrogen source. The invention also relates to copolymers that comprise the pyridinedicarboxylic acid monomers and derivatives thereof, processes for the formation of the copolymers and uses for the copolymers. | ||||||
