| Abstract |
The biodegradation of one popular nitramine energetics, Ammonium Dinitramide (ADN) by mixture of dentrifying bacterial species was investigated. ADN was observed to be effectively mineralized in the anaerobic mixed culture. The initial ADN concentration of 250㎎/L was reduced to non-detectable levels (>99% removal efficiency) in 5 days of incubation under anaerobic conditions. Final products generated from anaerobic degradation of nitramine energetics by anaerobic metabolism were NH₄^+, CH₄, and CO₂ that were released to the environment with the denitrifiers` growth. In addition, it was found that the activity of denitrifiers was inhibited by high concentration of ammonia generated through the degradation reactions of energetic nitrites. |
