Pure microbial cultures, one identified as Agrobacterium radiobacter, isolated under aerobic and nitrogen limiting conditions obtained from soil, river water, and sewage sludge were capable of metabolizing pentaerythritol tetranitrate. Enterobacter cloacae PB 2 isolated from a mixed microbial cultures obtained from soil under aerobic and nitrogen limited conditions was also capable of utilizing pentaerythritol tetranitrate sole nitrogen source. A proposed biodegradation pathway for pentaerythriol tetrenitrate initiated using Enterobacter cloacae proceeds via xenobiotic reductase to the trinitrate and then pentaerytrhitol dinitrate.
