Biological reduction of iodate: From research history to recent findings [in Japanese]

Amachi Seigo

… Iodine exists mainly as inorganic iodate (IO3−) and iodide (I−),although iodate is thermodynamically more stable than iodide in seawater. … This apparent thermodynamic disequilibrium is thought to be due to the activity of iodate reduction by algae and marine bacteria in ocean surface. … In particular, a hypothesis that iodate is reduced by nitrate reductase of marine organisms has been paid attention. …
