Reduction of 4-chloronitrobenzene by Azospirillum lipoferum
The strain of Azospirillum lipoferum which reduces 4-chloronitrobenzene under aerobic and anaerobic conditions was isolated from the soil. In experiments with 14C-ring-labeled 4-chloronitrobenzene, approximately 40% of the radioactive material disappeared from the growth medium after incubation under anaerobiosis within 48 hours, but under aerobic conditions only small decrease of radioactivity in the growth medium was observed. The major two metabolites produced from 4-chloronitrobenzene in a Azospirillum culture medium were isolated and characterized. These metabolites appear to be 4-chloroacetanilide and l,3-bis(p-chlorophenyl)triazene.
