In a medium without oxygen in the presence of nitrates, E. coli transforms p-chloranilin (p-CA) to yield a more hydrophilic compound which cannot be extracted with an organic solvent from water. The conditions for consecutive transformation of p-nitro-chlorobenzene (p-NCB) and p-CA have been determined: the reaction p-NCB leads to p-CA is inhibited by nitrates, p-CA transformation occurs in the presence of nitrates in the medium and depends on their concentration.
