ABSTRACT:
1,2-Dihydroxycyclohexa-3,5-diene-1,4-dicarboxylic acid and its salts, which are novel intermediates yielding hydroxyterephthalic acid upon dehydration, can be prepared by culturing terephthalic acid and a carbon/energy source with a microorganism capable of oxidizing terephthalic acid but incapable of degradation of 1,2-dihydroxycyclohexa-3,5-diene-1,4-dicarboxylic acid thereby formed.
