Bioremediation of radioactive waste or bioremediation of radionuclides is an application of bioremediation based on the use of biological agents bacteria, plants and fungi (natural or genetically modified) to catalyze chemical reactions that allow the decontamination of sites affected by radionuclides.

hyperaccumulators and contaminants : Al, Ag, As, Be, Cr, Cu, Mn, Hg, Mo, naphthalene, Pb, Se, Zn – accumulation rates ; Contaminant Accumulation rates (in mg/kg dry ...
Bioremediation can be used to mineralize organic pollutants, to partially transform the pollutants, or alter their mobility. Heavy metals and radionuclides generally cannot be biodegraded, but can be bio-transformed to less mobile forms.
Microbial biodegradation is the use of bioremediation and biotransformation methods to harness the naturally occurring ability of microbial xenobiotic metabolism to degrade, transform or accumulate environmental pollutants, including hydrocarbons (e.g. oil), polychlorinated biphenyls (PCBs), polyaromatic hydrocarbons (PAHs), heterocyclic compounds (such as pyridine or quinoline ...
Radionuclides: Fertilizing the soil with nitrogen if needed will indirectly increase the take-up of radionuclides by generally boosting the plant's overall growth and more specifically roots' growth. But some fertilizers such as K or Ca compete with the radionuclides for cation exchange sites, and will not increase the take-up of radionuclides.
Rock and dust samples retrieved by NASA from the asteroid Bennu exhibit some of the chemical building blocks of life, according to research that provides some of the best evidence to date that ...
Fungi such as Rhodotorula taiwanensis can possibly be used in the bioremediation of radioactive waste due to their low pH and radiation resistant properties. [67] Certain species of fungi are able to absorb and retain radionuclides such as 137 Cs, 121 Sr, 152 Eu, 239 Pu and 241 Am.
The U.S. Centers for Disease Control and Prevention and other federal health agencies on Friday took down webpages with information on HIV statistics and other data to comply with Trump ...
