微生物在自然界内种类繁多，并在重金属元素的生物地球化学循环中扮演着重要的角色。近年来，细菌与真菌对重金属的富集、转化作用成为此领域内的研究焦点。研究结果表明，细菌对重金属的富集、转化作用主要是通过胞壁吸附、氧化还原、细菌淋滤及与其它生物协同作用而进行的；真菌则主要是通过表面吸附与重金属硫蛋白的络合作用来富集环境中的重金属。文章对这些研究进展进行了综述，同时还介绍了菌根真菌在重金属的植物修复中所起的重要作用。 |

In the natural environment,there are various kinds of microboes,which play a key role in the bio-geochemical process of heavy metals.Recent studies have been focused on the absorption and transformation of heavy metals by bacteria and fungi.The results show that bacteria adsorbed the heavy metals mainly via biosorption,oxido-reduction,bioleaching and other synergisms,and fungi mainly via absorption and complexation with metallothionein.In addition,mycorrhiza fungi can also help the plants to biosorp heavy metals through metabolism. |
