Complete arsenic-based respiratory cycle in the marine microbial communities of pelagic oxygen-deficient zones [Environmental Sciences]

Microbial capacity to metabolize arsenic is ancient, arising in response to its pervasive presence in the environment, which was largely in the form of As(III) in the early anoxic ocean. Many biological arsenic transformations are aimed at mitigating toxicity; however, some microorganisms can respire compounds of this redox-sensitive element to...
