The removal of emerging organic contaminants from municipal wastewater poses a major challenge unsatisfactorily addressed by present wastewater treatment processes. Enzyme-catalyzed transformation of emerging organic contaminants (EOC) has been proposed as a possible solution to this major environmental issue more than a decade ago. Especially, laccases gained interest in this context in recent years due to their broad substrate range and since they only need molecular oxygen as a cosubstrate. In order to ensure the stability of the enzymes and allow their retention and reuse, either immobilization or insolubilization of the biocatalysts seems to be the prerequisite for continuous wastewater treatment applications. The present review summarizes the research conducted on EOC transformation with laccases and presents an overview of the possible immobilization techniques. The goal is to assess the state of the art and identify the next necessary steps that have to be undertaken in order to implement laccases as a tertiary wastewater treatment process in sewage treatment plants.
从市政废水中去除新兴有机污染物是当前废水处理工艺无法令人满意解决的主要挑战。十多年前，就有人提出利用酶催化转化新兴有机污染物（EOC）来解决这一主要的环境问题。近年来，由于漆酶具有广泛的底物范围，并且只需要分子氧作为共底物，因此在这方面引起了人们的兴趣。为了确保酶的稳定性并允许其保留和重复使用，似乎需要对生物催化剂进行固定化或不溶化，以便连续进行废水处理应用。本综述总结了用漆酶进行新兴有机污染物转化的研究，并概述了可能的固定化技术。其目的是评估该领域的现状，并确定为了将漆酶作为污水处理厂的三级废水处理工艺实施，必须采取的下一步措施。
