Arsenic metabolism by microbes in nature and the impact on arsenic remediation.
In nature, both prokaryotes and eukaryotes have evolved a wide spectrum of pathways such as oxidation/reduction, compartmentalization, exclusion, and immobilization [16] as the main natural defense mechanisms to arsenic. This review highlights our current understanding of the biochemistry and molecular biology involved in these natural arsenic metabolisms, and some successful examples of engineered microbes by harnessing these natural mechanisms for effective remediation.
