| 中文摘要 |
| 综述国内外有关苯二甲酸酯(PAEs)化合物对环境的污染以及微生物对该类物质的降解与转化。指出:①PAEs已在全球范围的大气、水体、土壤中达到了普遍检出的程度;②微生物能够降解利用PAEs;③PAEs的微生物降解反应速率符合一级反应动力学方程;④混合微生物的联合代谢作用较纯培养降解PAEs效果好;⑤PAEs在微生物酶的作用下,先水解生成单酯与本二甲酸,然后在好气条件下进行代谢与转化,最终可生成CO2和水。 |
| 英文摘要 |
| The environmental Pollution by phthalic acid esters (PAEs) and their degradation and transformation by micro-organism reported at home and abroad, were reviewed with the following conclusions:(1)PAEs have been ubiguitously detected in air, ground,river,drinking water and other waters in the world;(2)Micro-organisms can degrade PAEs and utilize them;(3) Reaction rate of microbial PAEs degradation can follow the first order reaction kineticsi (4) Combined meta-bolization of mixed micro-organisms in PAEs biodegradation is better than pure culture effect; (5) PAEs are hydrolyzed by microbial enzymes to monoester and phthalic acid,then can be metabolized and transformed under aerobic conditions, at last degraded to CO2 and water. |
