Aerobic degradation of dinitrotoluenes and pathway for bacterial degradation of 2,6-dinitrotoluene.
An oxidative pathway for the mineralization of 2,4-dinitrotoluene (2, 4-DNT) by Burkholderia sp. strain DNT has been reported previously. We report here the isolation of additional strains with the ability to mineralize 2,4-DNT by the same pathway and the isolation and characterization of bacterial strains that mineralize 2, 6-dinitrotoluene (2,6-DNT) by a different pathway. Burkholderia cepaci...
متن کاملCytotoxicity and Expression of c-fos, HSP70, and GADD45/153 Proteins in Human Liver Carcinoma (HepG2) Cells Exposed to Dinitrotoluenes
Dinitrotoluenes (DNTs) are byproducts of the explosive trinitrotoluene (TNT), and exist as a mixture of 2 to 6 isomers, with 2,4-DNT and 2,6-DNT being the most significant. The main route of human exposure at ammunition facilities is inhalation. The primary targets of DNTs toxicity are the hematopoietic system, cardiovascular system, nervous system and reproductive system. In factory workers, e...

متن کاملCytotoxicity, Oxidative Stress, and Genotoxicity in Human Liver Carcinoma (hepg2) Cells Exposed to Dinitrotoluenes
Dinitrotoluenes (DNTs) [CH3C6H3(NO2)2] are nitroaromatic compounds that are produced industrially and released into the environment as a result of human activities. DNTs appear as pale yellow crystalline solids and exist as a mixture of 2 to 6 isomers, among which 2,4-DNT and 2,6-DNT are the most significant The primary targets of DNTs toxicity are the hematopoietic system, cardiovascular syste...
متن کاملAnaerobic Biotransformation of 2,4-Dinitrotoluene and 2,6-Dinitrotoluene by Clostridium acetobutylicum: A Pathway through Dihydroxylamino Intermediates
Experiments were conducted to isolate and identify the intermediates and products of 2,4-dinitrotoluene and 2,6dinitrotoluene metabolism by Clostridium acetobutylicum. Transformation of both dinitrotoluenes initially resulted in the formation of hydroxylaminonitrotoluenes. Subsequent transformation favored the formation of dihydroxylaminotoluenes, with a limited reduction to aminonitrotoluene i...
