摘要
Several bacterial strains were examined for their ability to degrade the nitroaromatic explosive 2,4,6-trinitrotoluene (TNT). The strains examined included various clostridial strains isolated from a 4-year-old munition enrichment, related clostridial strains obtained from a culture collection, two enteric bacteria, and three lactobacilli. All Clostridium species tested were able to reduce TNT rapidly in a complex medium. In cell suspension experiments, these strains were also able to reduce 2,4-diamino-6-nitrotoluene (DANT) to 2,4,6-triaminotoluene (TAT) and to produce a compound that is not yet identified; thus, they could not be distinguished from one another with regard to the pathway of transformation, The enteric strains and the lactobacilli were able to perform the initial reduction of TNT, but none was capable of reducing DANT in cell suspensions.
