Bacteria mediate methylation of iodine in marine and terrestrial environments

Article Abstract:

Many bacteria can methylate iodine, forming methyl iodide. Rhizobium sp. strain MRCD 19 uses S-adenosyl-L-methionine as the methyl donor.

Active transport and accumulation of iodide by newly isolated marine bacteria

Article Abstract:

Increased iodide content but decreased concentration factor for iodide were observed in the presence of much higher concentrations of iodide. An iodide transport assay was carried out to monitor the uptake and accumulation of iodide in washed cell suspensions of iodide-accumulating bacteria.

Hydrogen peroxide-dependent uptake of iodine by marine Flavobacteriaceae bacterium strain C-21

Article Abstract:

A radioactive iodide tracer is used to study the detailed mechanism of iodine uptake by the cells of the marine bacterium strain C-21. The findings reveal that uptake of iodine is influenced by hydrogen peroxide produced by glucose oxidase.
