摘要

集约化养殖生产通常会诱导17β-雌二醇（E2）的积累，导致鱼类内分泌紊乱和雌性化，对水产品的质量安全构成巨大威胁。生物处理在消除E2中起关键作用。本综述通过查阅文献，收集水产养殖废水生物处理过程中E2的各种去除途径（物理吸附、生物降解等途径）的信息。本文从降解的功能微生物、分子机制和降解途径等方面论述了降解的重要作用。提出了不同途径对E2去除的贡献，包括生物方法。最后，提出了今后在加强E2消除方面弥合知识空白的研究方向。

Biodegradation mechanism and removal routes of 17β-estradiol in aquaculture wastewater: A review

Intensive aquaculture production usually induces the accumulation of 17β-estradiol (E2), which causes endocrine disorders and feminization of fish, posing a huge threat to the quality and safety of aquatic products. Biological treatment plays a critical role in eliminating E2. For the purpose of this review, a thorough search of the literature was conducted to collect information on the various E2 removal routes (i.e. physical adsorption, biodegradation, and other routes) during biological treatment of aquaculture wastewater. The review discusses the vital role of degradation with respect to the functioning microorganisms, molecular mechanisms and degradation pathways. The contribution of different routes to E2 removal involved in biological approaches is presented. Finally, future research directions on bridging knowledge gaps for enhancing E2 elimination are proposed.

期刊介绍： Aquacultural Engineering is concerned with the design and development of effective aquacultural systems for marine and freshwater facilities. The journal aims to apply the knowledge gained from basic research which potentially can be translated into commercial operations. Problems of scale-up and application of research data involve many parameters, both physical and biological, making it difficult to anticipate the interaction between the unit processes and the cultured animals. Aquacultural Engineering aims to develop this bioengineering interface for aquaculture and welcomes contributions in the following areas: – Engineering and design of aquaculture facilities – Engineering-based research studies – Construction experience and techniques – In-service experience, commissioning, operation – Materials selection and their uses – Quantification of biological data and constraints
