Iodate Reduction by Shewanella oneidensis Requires Genes Encoding an Extracellular Dimethylsulfoxide Reductase.

ABSTRACT: Microbial iodate (IO₃ ^-) reduction is a major component of the iodine biogeochemical reaction network in anaerobic marine basins and radioactive iodine-contaminated subsurface environments. Alternative iodine remediation technologies include microbial reduction of IO₃ ^- to iodide (I^-) and microbial methylation of I^- to volatile gases. The metal reduction pathway is required for anaerobic IO₃ ^- respiration by the gammaproteobacterium Shewanella oneidensis. However, the terminal IO₃ ^- reductase and additional enzymes involved in the S. oneidensis IO₃ ^- electron transport chain have not yet been identified. In this study, gene deletion mutants defic
