Experimental Investigations and Kinetic Models for the Cometabolic Biological Reduction of Trinitrotoluene

Soils contaminated with the explosive trinitrotoluene can be remediated in a soil slurry process by adding easily degradable substrates. During the anaerobic fermentation of these substrates TNT is biologically reduced to metabolites which subsequently are immobilized in the soil by chemical reactio...

Description
Summary:Soils contaminated with the explosive trinitrotoluene can be remediated in a soil slurry process by adding easily degradable substrates. During the anaerobic fermentation of these substrates TNT is biologically reduced to metabolites which subsequently are immobilized in the soil by chemical reactions with soil components. Experimental investigations revealed that the cometabolic yield varied strongly with process conditions and could be increased by a factor of 10. Efforts to model this process were only partially successful as details underlying cometabolism are still unknown.
