Bj. Vanderwoude et al., ANAEROBIC DEGRADATION OF HALOGENATED BENZOIC-ACIDS BY PHOTOHETEROTROPHIC BACTERIA, FEMS microbiology letters, 119(1-2), 1994, pp. 199-207
From light-exposed enrichment cultures containing benzoate and a mixtu
re 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 identi
fied as a Rhodopseudomonas palustris strain. It differs from Rhodopseu
domonas 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.
