Iodine Biogeochemical Cycle and Microbial Bioremediation of Radioactive Iodine-129.
Review in Journal of microbiology and biotechnology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Iodine is an essential biophilic element that plays pivotal roles in both environmental systems and human physiology, particularly as a key constituent of thyroid hormones and a regulator of atmospheric ozone. In contrast, its radioactive isotope, iodine-129 (I-129), predominantly generated through anthropogenic nuclear activities, represents a persistent environmental and public health concern. With an exceptionally long half-life of approximately 15.7 million years and high environmental mobility, especially in groundwater, combined with a strong tendency to bioaccumulate in the human thyroid, I-129 poses a disproportionate and long-term radiological hazard in contaminated sites. The biogeochemical cycling of iodine involves intricate interconversions among multiple oxidation states and phases across the lithosphere, hydrosphere, atmosphere, and biosphere. Microorganisms are central to these processes, mediating oxidation, reduction, methylation, accumulation, and sorption. While microbial methylation can increase I-129 mobility via the production of volatile methyl iodide, other microbial pathways, notably biosorption and binding to organic matter, provide promising mechanisms for immobilization and natural attenuation. Microbial bioremediation offers a sustainable and cost-effective alternative or complement to conventional physicochemical methods for managing radioactive contaminants. Strategies such as bioreduction, biosorption, bioaccumulation, and biomineralization exploit the metabolic versatility of microorganisms to alter radionuclide speciation, solubility, and mobility. However, practical application to I-129 remains challenging due to its extreme persistence, environmental variability, and uncertainties in predicting its long-term geochemical fate. Effective management of I-129 contamination will require an integrated, multidisciplinary approach that combines advanced microbial ecology insights, optimized biotechnological processes, and long-term monitoring frameworks.
