Microorganisms and Explosives: Mechanisms of Nitrogen Release from TNT for Use as an N-Source for Growth
Unstable reduced derivatives of 2,4,6-trinitrotoluene (TNT) produced by microorganisms have been found to release nitrite by rearomatization and/or condensation. Here, we present further information regarding the novel mechanism of the condensation of reactive hydroxylaminodinitrotoluene and the Mei...

| description | Unstable reduced derivatives of 2,4,6-trinitrotoluene (TNT) produced by microorganisms have been found to release nitrite by rearomatization and/or condensation. Here, we present further information regarding the novel mechanism of the condensation of reactive hydroxylaminodinitrotoluene and the Meisenheimer dihydride complex of TNT to produce two secondary diarylamine isomers. Using uniformly 15N-labeled (15N3) TNT, we show that the nitrite is being released by the condensation reaction and, also under environmental conditions, will originate from the microbiologically generated dihydride complex. |
