摘　　要：硝基酚是一类重要且常用的化工原料,一些硝基酚毒性大且难以生物降解,被美国环保局列入“优先控制污染物名单”。在自然环境条件下,硝基酚的生物降解速率缓慢,导致硝基酚在环境中长期滞留和积累。分析了人工强化条件下废水中硝基酚的生物降解性能,主要从具有降解硝基酚能力的微生物、硝基酚的厌氧生物降解性、硝基酚的好氧生物降解性和硝基酚的共基质代谢降解方面进行了较全面的综述,讨论了该研究当前仍存在的一些问题和研究展望。Nitrophenols are among the most important and versatile industrial organic compounds. Several nitrophenols can be highly toxic and refractory and were listed on the U.S. Environmental Protection Agency＇s ＂Priority Pollutants List＂. In natural environments, nitrophenols are not easily biodegraded and may stay indefi- nitely in the environment. This paper reviews the research advances of biodegradability of nitrophenols under artificial conditions. The extensive efforts have been made to discuss the microorganisms able to transform nitrophenols, the research of anaerobic, aerobic and co-metabolic biodegradation of nitrophenols. At the meantime the shortages and trends of the research are analyzed.
