深海抗铬(Ⅵ)细菌的分离、鉴定及其铬(Ⅵ)还原能力的研究
Isolation and identification of chromate-tolerant deep-sea bacteria and their chromate reduction capability
-
摘要: 随着采矿业的发展和重金属在工农业等诸多领域的应用,排放到环境中的含重金属离子的废水大大增加.重金属进入环境后不能被生物降解而只能发生各种形态间的相互转化和迁移,当被低等生物富集后,通过食物链进入人体,破坏生物体正常的生理代谢活动,危害人体健康.业已发现,许多微生物能在较高浓度的金属离子环境中生存,并解除重金属对自身的毒害[1],这一点可被应用于金属污染环境的生物修复和贵重金属的生物沥滤等方面.
