WebMicrobial 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. WebIn this study, an iodate-reducing bacterium, designated strain SCT, was newly isolated from marine sediment slurry. SCT is phylogenetically closely related to the denitrifying bacterium Pseudomonas stutzeri and reduced 200 microM iodate to iodide (I (-)) within 12 h in an anaerobic culture containing 10 mM nitrate.

Outside of the upwelling area, R-iodate and R-iodide did not correlate well with NRA, probably as a result of the masking effect of mixing among …

Web28 dec. 2024 · Based on genetic and physiological 16 data, IO 3 -is likely reduced to hypoiodous acid (HIO), which rapidly disproportionates into IO 3 - 17 and iodide (I-), in a respiratory pathway that provides an energy yield equivalent to that of nitrate 18 or perchlorate respiration.

Web1 nov. 2015 · Bacterial interactions with iodine have been studied, and show that iodate can be reduced directly by iron- and sulfate-reducing bacteria under axenic conditions. Indeed, in one early study, sulfate-reducing species were able to reduce up to 96% of iodate to iodide in matter of hours ( Councell et al., 1997 ). 70坦克Redox Iodate is one of several oxyanions of iodine, and has an oxidation number of +5. It participates in several redox reactions, such as the iodine clock reaction. Iodate shows no tendency to disproportionate to periodate and iodide, in contrast to the situation for chlorate.
