摘要

Microbial biomineralization presents a promising strategy for the eco-friendly immobilization of uranium. This review systematically examines the mechanisms, advancements, and environmental influences of three primary uranium mineralization pathways: Microbially Induced Carbonate Precipitation (MICP), Microbially Induced Phosphate Precipitation (MIPP), and reductive mineralization mediated by uranium-reducing bacteria. Each pathway faces bottlenecks: unstable MICP products, MIPP confined to laboratory scale, and low in-situ efficiency of uranium-reducing bacteria. Future research should deepen mechanism exploration, construct functional bacterial consortia, and develop synergistic technologies to promote engineering applications.
