We have isolated two soil bacteria (identified as Arthrobacter aurescens TW17 and Nocardia sp. strain TW2) capable of degrading p-nitrophenol (PNP) and numerous other phenolic compounds. A. aurescens TW17 contains a large plasmid which correlated with the PNP degradation phenotype. Degradation of PNP by A. aurescens TW17 was induced by preexposure to PNP, 4-nitrocatechol, 3-methyl-4-nitrophenol, or m-nitrophenol, whereas PNP degradation by Nocardia sp. strain TW2 was induced by PNP, 4-nitrocatechol, phenol, p-cresol, or m-nitrophenol. A. aurescens TW17 initially degraded PNP to hydroquinone and nitrite. Nocardia sp. strain TW2 initially converted PNP to hydroquinone or 4-nitrocatechol, depending upon the inducing compound.
我们分离出了两种能够降解对硝基苯酚(PNP)及许多其他酚类化合物的土壤细菌(鉴定为金色节杆菌TW17和诺卡氏菌属菌株TW2)。金色节杆菌TW17含有一个与PNP降解表型相关的大质粒。金色节杆菌TW17对PNP的降解可通过预先暴露于PNP、4-硝基邻苯二酚、3-甲基-4-硝基苯酚或间硝基苯酚来诱导,而诺卡氏菌属菌株TW2对PNP的降解则可由PNP、4-硝基邻苯二酚、苯酚、对甲酚或间硝基苯酚诱导。金色节杆菌TW17最初将PNP降解为对苯二酚和亚硝酸盐。诺卡氏菌属菌株TW2最初根据诱导化合物的不同将PNP转化为对苯二酚或4-硝基邻苯二酚。
