A novel Methylomirabilota methanotroph potentially couples methane oxidation to iodate reduction [PDF]
mLife, 2022 Impact statementMethane oxidizing microbes play a key role in reducing the emission of this potent greenhouse gas to the atmosphere. The known versatility of the recently discovered anaerobic Methylomirabilota methanotrophs is limited. Here, we report a novel uncultured Methylomirabilis species, Candidatus Methylomirabilis iodofontis, with the genetic ...

Iodate reduction by marine aerobic bacteria [PDF]
Frontiers in MicrobiologyIodate reductase (Idr) gene cluster (idrABP1P2) is involved in bacterial iodate (IO3−) respiration under anaerobic conditions. Putative idr gene clusters are present in both anaerobic and aerobic bacteria; however, the specific physiological roles of idr

Metal Reduction and Protein Secretion Genes Required for Iodate Reduction by Shewanella oneidensis. [PDF]
Appl Environ Microbiol, 2019 Microbial iodate (IO3−) reduction is a major component in the biogeochemical cycling of iodine and the bioremediation of iodine-contaminated environments; however, the molecular mechanism of microbial IO3−reduction is poorly understood. Results of the present study indicate that outer membrane (type II) protein secretion and metal reduction genes ...

Rice (<i>Oryza sativa</i> L.) roots have iodate reduction activity in response to iodine [PDF]
Frontiers in Plant Science, 2013 Although iodine is not an essential nutrient for higher plants, their roots take up and transport the element. However, the exact mechanisms involved in iodine uptake and metabolism in higher plants have yet to be elucidated.

Global occurrence of the bacteria with capability for extracellular reduction of iodate
Frontiers in Microbiology, 2022 The γ-proteobacterium Shewanella oneidensis MR-1 reduces iodate to iodide extracellularly. Both dmsEFAB and mtrCAB gene clusters are involved in extracellular reduction of iodate by S. oneidensis MR-1.

The dmsEFABGH operon encodes an essential and modular electron transfer pathway for extracellular iodate reduction by Shewanella oneidensis MR-1 [PDF]
Microbiology SpectrumExtracellular iodate reduction by Shewanella spp. contributes to iodide generation in the biogeochemical cycling of iodine. However, there is a disagreement on whether Shewanella spp. use different extracellular electron transfer pathways with dependence

Iodine Activation from Iodate Reduction in Aqueous Films via Photocatalyzed and Dark Reactions. [PDF]
ACS Earth Space ChemIodine in the atmosphere destroys ozone and can nucleate particles by formation of iodic acid, HIO3. Recent field observations suggest iodate recycles from particles sustaining significant gas-phase IO radical concentrations (0.06 pptv) in aged stratospheric air, and in elevated dust plumes.

Senescence as the main driver of iodide release from a diverse range of marine phytoplankton [PDF]
Biogeosciences, 2020 The reaction between ozone and iodide at the sea surface is now known to be an important part of atmospheric ozone cycling, causing ozone deposition and the release of ozone-depleting reactive iodine to the atmosphere.

Modelling iodide – iodate speciation in atmospheric aerosol: Contributions of inorganic and organic iodine chemistry [PDF]
Atmospheric Chemistry and Physics, 2007 The speciation of iodine in atmospheric aerosol is currently poorly understood. Models predict negligible iodide concentrations but accumulation of iodate in aerosol, both of which is not confirmed by recent measurements.
