From light‐exposed enrichment cultures containing benzoate and a mixture of chlorobenzoates, a pure culture was obtained able to grow with 3‐chlorobenzoate (3‐CBA) or 3‐bromobenzoate (3‐BrBA) as the sole growth substrate anaerobically in the light. The thus isolated organism is a photoheterotroph, designated isolate DCP3. It is preliminarily identified as a Rhodopseudomonas palustris strain. It differs from Rhodopseudomonas palustris WS17, the only other known photoheterotroph capable of using 3‐CBA for growth, in its independence of benzoate for growth with 3‐CBA and in its wider substrate range: if grown on 3‐CBA, it can also use 2‐CBA, 4‐CBA or 3,5‐CBA.
