Biodegradation of Alpha TNT and Its Production Isomers

Abstract

Gram negative bacteria have been isolated from several sources which use 2,4,6-trinitrotoluene (alpha-TNT) as the sole source of carbon and nitrogen for growth. There is a direct relationship between the alpha-TNT concentration in the growth medium and growth response of isolate I-2WT as well as the percentage of TNT degradation by this organism. Studies using ring UL-14C-TNT suggested possible ring cleavage (biodegradation) of TNT as 14C activity was released as carbon dioxide and also found in the cells. Heterotrophic carbon dioxide fixation was demonstrated using NaH(14)CO3 added to a culture growing on unlabeled TNT.
