A newly isolated Arthrobacter ureafaciens , strain CPR706, could degrade 4‐chlorophenol via a new pathway, in which the chloro‐substituent was eliminated in the first step and hydroquinone was produced as a transient intermediate. Strain CPR 706 exhibited much higher substrate tolerance and degradation rate than other strains that degraded 4‐chlorophenol by the hydroxylation at the second carbon position to form chlorocatechol. Strain CPR706 could also degrade other para ‐substituted phenols (4‐nitro‐, 4‐bromo‐, 4‐iodo‐, and 4‐fluoro‐phenol) via the hyroquinone pathway.
