Iodate reduction
Web1 feb. 2005 · Although iodine is harmful to plants, rice plants (Oryza sativa L.) absorbed iodine more selectively than bromine. To explain this selective absorption, the authors proposed the following hypothesis based on the fact that the standard redox potential for (I2+ 2e = 2I−) is lower than that for (Br2+ 2e = 2Br−) and (Fe3++ e = Fe2+), and the … Web17 aug. 2024 · 该研究结果扩展了Methylomirabilota甲烷氧化细菌代谢的多样性，并为一种新的潜在的甲烷氧化过程——碘酸盐驱动的AOM提供了基因组方面的证据。

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. Web17 jan. 2024 · Recent reports of dissimilatory iodate-reducing microorganisms (DIRM) have arisen from studies of bacteria in marine environments. These studies described the …
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 ).
