砷污染微生物修复的进展研究

随着工业的快速发展,砷污染成为全世界尤其是发展中国家面临的主要环境问题之一.微生物修复是砷污染修复的重要技术,本文在微生物对砷的专性吸附,微生物对砷的形态转化及含砷化合物的降解和挥发,微生物-根系互作对土壤砷污染的影响,及微生物砷修复的分子生物学等4个方面阐述了微生物砷修复机制的研究进展.文章还对微生物砷污染修复进行了...

Current Researches in Microbial Remediation of Arsenic Pollution

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.
