Abstract
This study was carried out to explore the lowest achievable dinitrotoluene (DNT) isomer concentrations that would support sustained growth of DNT degrading microorganisms under an aerobic condition. Studies were conducted using suspended (chemostat) and attached growth (column) systems. The biodegradation limits for 2,4-dinitrotoluene chemostat and column system were 0.054 +/- 0.005 and 0.057 +/- 0.008 mu M, respectively, and for 2,6-dinitrotoluene, the limits for chemostat and column system were 0.039 +/- 0.005 and 0.026 +/- 0.013 mu M, respectively. The biodegradation limits determined in this study are much lower than the regulatory requirements, inferring that bacterial ability to metabolize DNT does not preclude applications of bioremediation (including natural attenuation) for DNT contaminated media.
