| Outline of Final Research Achievements |
Terephthalic acid is used in various fields as a raw material for PET bottles, polyester fibers, and functional films for LCD panels. In the recycling of these products, liquid waste containing terephthalic acid is generated, and its treatment has become a problem. In this study, we identified relevant genes and analyzed the metabolic pathways of terephthalic acid-degrading bacteria (strain TB-97) based on the whole genome information, with the aim of producing useful substances (e.g. PDC) from terephthalic acid. We also determined the structure of a novel metal-recovery substance (siderophore) produced by this strain, and investigated the relationship between the microbial community structure and terephthalic acid degradation in the activated sludge tank from which this strain was isolated.
