growth experiments and oxygen uptake rates with other chlorinated aromatic compounds revealed a high degree of specificity of the initial dioxygenase . cis-1,2-dihydroxycyclohexa-3,5-diene oxidoreductase and 1,2-pyrocatechase , but not 2,3-pyrocatechase , were found in cell extracts , while 3,6-dichlorocatechol and ( 2,5-dichloro ) muconic acid could be detected as intermediates during degradation of 1,4-dichlorobenzene .
