| Outline of Final Research Achievements |
Aromatic polymers are widely used in plastic industries. One property common to these polymers is their resistance to bio-degradation and, despite its importance, there are only a few reports on aromatic polymer-degrading microorganism or enzymes. In this study, we used 4CDP, a recently developed aromatic polymer, as a model substrate and screened for microorganisms or enzymes that can degrade aromatic polymers. We found that a fungus in the genus Aspergillus produces some enzyme that hydrolyzes 4CDP. Moreover, we succeeded in purifying the enzyme from an Aspergillus-originated material and identifying the gene encoding the enzyme. We expect that knowledge on this enzyme will contribute to development of aromatic polymer-recycling system, which is to be materialized in the future.
