Description:
Four methanogenic consortia, which degraded 2-chlorophenol, 3-chlorophenol, 2-chlorobenzoate, and 3-chlorobenzoate, respectively; and one nitrate-reducing consortium which degraded 3-chlorobenzoate were characterized. Degradative activity in these consortia has been maintained in laboratory transfer for over two years. In the methanogenic consortia, the aromatic ring was dechlorinated before mineralization to methane and carbon dioxide. fter dechlorination, the chlorophenol consortia converted phenol to benzoate beforemineralization. All methanogenic consortia degraded both phenol and benzoate. The 3-chlorophenol and 3-chlorobenzoate consortia also degraded 2-chlorophenol. No other cross acclimation to monochlorophenols or monochlorobenzoates was detected in the methanogenic consortia. The consortium which required nitrate for the degradation of 3-chlorobenzoate degraded benzoate and 4-chlorobenzoate anaerobically in the presence of KN03, but not in its absence. his consortium also degraded benzoate, but not 3-chlorobenzoate, aerobically.
