Printed circuit boards (PCBs) as the indispensable accessories of electronic product had the characters of complex component,harmful to environment and high recycling value,so effectively extracted and purified the efficacious component from waste PCBs had always been the focus and difficult problems in waste electric and electronic equipment (WEEE) treatment. Bioleaching of metal in PCBs was an environmental friendly method in WEEE recycling and it had attracted wide attention. In this paper,the recent researches of bioleaching PCBs were presented,including the type of main used microbe,reaction mechanism and influence factors and so on. At last,an outlook of future research was proposed.%印刷线路板作为电子产品中不可缺少的部件,具有成分复杂、环境危害大和资源化价值高等特点,对废印刷线路板成分进行科学有效地分离富集一直是电子废弃物资源化利用研究的热点和难点.从适用的微生物种类、微生物的浸提机制、影响微生物浸提效果的因素等方面综述了微生物在印刷线路板中金属的浸出中的应用研究状况,最后对未来的研究方向进行了展望.
