Formation of aniline as a transient metabolite during the metabolism of tetryl by a sulfate-reducing bacterial consortium.
A laboratory study was conducted to determine whether tetryl (2,4,6-trinitrophenylmethylnitramine) can be degraded by an anaerobic process. The results indicated that the metabolic conversion of tetryl to aniline is possible by a sulfate-reducing bacterial (SRB) consortium. This SRB consortium metabolized tetryl by co-metabolism with pyruvate as a growth substrate. For every mole of tetryl metabolized, 1 mole of aniline was produced, and the aniline was further metabolized. This metabolic conversion of tetryl is likely to be of value in the anaerobic treatment of tetryl-contaminated soil and ground water, such as found at many military ammunition sites.
