Under nitrate-reducing, nongrowth conditions, a Pseudomonas fluorescens species reduced 2,4,6-trinitrotoluene to aminodinitrotoluenes, which were then further reduced to diaminonitrotoluenes. 2,4-Diamino-6-nitrotoluene (2,4-DANT) was further transformed to a novel metabolite, 4-N-acetylamino-2-amino-6-nitrotoluene (4-N-AcANT), while 2,6-diamino-4-nitrotoluene (2,6-DANT) was persistent. Efforts to further degrade 2,4-DANT and 2,6-DANT under aerobic, nitrogen-limited conditions were unsuccessful; 2,6-DANT remained persistent, and 2,4-DANT was again transformed to the 4-N-AcANT compound.
在硝酸盐还原、非生长条件下,一种荧光假单胞菌将2,4,6-三硝基甲苯还原为氨基二硝基甲苯,然后进一步还原为二氨基硝基甲苯。2,4-二氨基-6-硝基甲苯(2,4-DANT)进一步转化为一种新型代谢物4-N-乙酰氨基-2-氨基-6-硝基甲苯(4-N-AcANT),而2,6-二氨基-4-硝基甲苯(2,6-DANT)则具有持久性。在有氧、氮限制条件下进一步降解2,4-DANT和2,6-DANT的尝试未成功;2,6-DANT仍具有持久性,2,4-DANT再次转化为4-N-AcANT化合物。
