| titleOfInvention | Method for producing useful chemical substance from terephthalic acid potassium salt |
| abstract | TPA-DHD can be produced by using, as a raw material, terephthalic acid salt that contains 0.5 times or more and twice or less the amount of potassium based on all of the terephthalic acids contained in the terephthalic acid salt in terms of moles and by using a microorganism expressing terephthalate 1,2-dioxygenase. Further, TPA-DHD can be converted into protocatechuic acid by TPA-DHD dehydrogenase and protocatechuic acid can be converted into gallic acid by para-hydroxybenzoate hydroxylase. In addition, by subjecting waste polyesters to heat treatment in an ethylene glycol solvent or 1-butanol solvent containing potassium hydroxide, such polyesters can be efficiently depolymeried, and potassium terephthalate suitable to chemical production by the microorganism can be prepared. |
