摘要
我国稀土矿山长期以来的无序开采甚至盗采现象致使稀土离子及其化合物不断进入到土壤、水体,造成了严重的生态和环境问题.稀土元素具有毒物刺激效应(Homesis效应),进入环境后影响动植物、微生物的生长、发育及繁殖,其造成的潜在危害引起了研究者对稀土生物效应的重视.文中从稀土元素与微生物的相互作用入手阐述其生物效应,概括了微生物应答稀土元素的胁迫反应,微生物对稀土元素的吸附作用,以及微生物与稀土作用的可能机制等方面的研究内容,并结合已有的研究成果,展望了微生物在稀土领域的应用基础研究方向及其面临的挑战.
Because of the disorderly exploitation and even illegal mining of rare earth elements, the ions and compounds continuously enter soil and water, resulting in serious ecological and environmental problems. The homesis-effect of rare earth elements greatly affects the growth, development and production of animals, plants and microorganisms, of which the potential threats cause much attention from researchers. This paper presents a summary of the interactions of microorganisms and rear earth ions and their compounds, and describes microbial stress response to rear earth elements, the microbial adsorption of rare earth elements, and the possible interaction mechanisms between rare earth and microorganisms. Combined with the current progress,this paper also previews the future research topics and the challenges of the basic research of microorganisms applied in the field of rare earth.
