Pseudomonas sp. and Pseudomonas putida can utilize dinitrotoluene (DNT) as N-source after the enzymatic removal of nitro groups from the aromatic ring. Addition of nutrients is known to stimulate the biodegradation process. Poultry litter has consortia of microorganisms (including Pseudomonas) along with many nutrients. The objective of this research was to study the biodegradation of 2,4- and 2,6-DNT contaminated soil (from Badger Army Ammunition Plant) using poultry litter. Complete biodegradation of both 2,4- and 2,6-DNT in the soil was observed after 1-day interaction with poultry litter. No degradation was observed using autoclaved litter.
假单胞菌属细菌和恶臭假单胞菌能够在从芳香环上酶促去除硝基后，将二硝基甲苯（DNT）用作氮源。已知添加营养物质可刺激生物降解过程。家禽粪便含有微生物群落（包括假单胞菌）以及许多营养物质。本研究的目的是利用家禽粪便研究受2,4-二硝基甲苯和2,6-二硝基甲苯污染的土壤（来自獾军弹药厂）的生物降解情况。与家禽粪便接触1天后，观察到土壤中2,4-二硝基甲苯和2,6-二硝基甲苯均完全降解。使用经高压灭菌的粪便未观察到降解现象。
