合成有机化合物的生物降解性研究

合成有机化合物的生物降解性研究,为预测各类化合物在环境中的滞留与影响,为某些化合物的生产、实用及向环境中排放提供立法的依据,以及对开发更有效的生物处理技术均有重要意义。本文从合成有机化合物生物降解性研究的意义、研究方法、化合物化学组成和结构与生物降解性的关系等方面,介绍了国内外研究工作的进展情况,并对苯及烷基苯类、芳香酸及其脂类、酚类、含氯有机物和含氮芳香化合物的生物降解规律和降解途径进行了综述。

A SURVEY ON THE MICROBIAL DEGRADATION OF SYNTHETIC ORGANIC COMPOUNDS

The microbial degradation of organic compounds is a very important subject in predicting their performances in environments and developing efficient biotreatment technologies.In this article, a brief introduction was given on the methods in studying the biodegradation of organic compounds, as well as relation between molecular structures and biodegradabilities,and the proposed degrada-tive pathways. The biodegradabilities and metabolic pathways of benzene and alkylbenzene, aromatics acids and their esters, phenols, chlorinated aromatic compounds, and nitrogen aromatic compounds were also summarized.
