Along with the rapid development of industries, arsenic contamination emerges as one of the world's most urgent environmental problems, especially for the developing countries. Microbial remediation of arsenic polluted environments is a key technique in practice, four aspects, i.e., the special adsorption of arsenic by micro-organisms, the transformation of arsenic speciation and the degradation and volatilization of arsenic compounds by micro-organisms, the effects to arsenic contamination of soil by the interactions between micro-organisms and plant roots, and the molecular biological mechanism of bioremediation for arsenic were reviewed in this paper. In the final section of this paper, the outlook of bioremediation for arsenic and the issues and realms which call for more researches in the future were discussed.
随着工业的快速发展,砷污染成为世界上最紧迫的环境问题之一,对发展中国家而言尤为如此。砷污染环境的微生物修复是一项关键实用技术,本文综述了微生物对砷的特殊吸附、砷形态的转化以及微生物对砷化合物的降解和挥发、微生物与植物根系相互作用对土壤砷污染的影响、砷生物修复的分子生物学机制这四个方面。在本文的最后部分,讨论了砷生物修复的前景以及未来需要更多研究的问题和领域。
