Research Advances in Microbial Biogeochemical Cycling of Uranium
Uranium is a widely distributed radioactive heavy metal on Earth,and its geochemical cycling is regulated by various microorganisms.This paper critically reviews the roles of microbes in the transformation of uranium species,including reductive immobilization,non-reductive immobilization,oxidative migration,and non-oxidative migration.By exploring the interaction between uranium and microorganisms in natural environments,a profound understanding of uranium migration,transformation,and enrichment mechanisms is achieved,thereby providing guiding insights for the exploration of uranium resources,the safe disposal of radioactive uranium-containing waste,and the remediation of heavy metal uranium pollution.
