Nitramine explosive degrading and mineralizing activity of indigenous microbial population in anaerobic sludge and soil were studied in microcosm tests under various conditions. lndigenous microbial populations in soil from an explosive contaminated site were unable to mineralize RDX or HMX to any great extent. In contrast, supplements of anaerobic sludge in soil slurry microcosms significantly enhanced the mineralization extent of RDX (800 ppm) and HMX (267 ppm) up to 60%. The anoxie bioslurry process degraded nitramine explosive rapidly and is considered as a feasible technology for the remediation of nitramine explosive highly contaminated soil.
