摘要 微生物砷氧化是指微生物通过砷氧化酶AioAB将毒性强的亚砷酸盐[As(Ⅲ)]氧化为毒性较弱的砷酸盐[As(Ⅴ)]的过程。该过程一方面有利于微生物自身和环境的修复,另一方面能够提供能量供给部分砷氧化菌生长。介绍微生物砷氧化调控机制的最新研究进展。 Microbial arsenite oxidation is a mechanism which could oxidize the more toxic As (Ⅲ) to the less toxic As (Ⅴ) by arsenite oxidase AioAB.Such detoxification process is beneficial for microorganism and also useful for environmental bioremediation.Some arsenite-oxidizing microorganisms can use the energy produced by As(Ⅲ) oxidation to support their growth.Here we summarize the recent research progress of the regulation mechanism of microbial arsenite oxidation.
