Controlling uranium species to its long-term stability in bioremediation

该项目旨在揭示好氧和厌氧生物修复条件下铀的转化和固定化机理，重点阐明在不同途径和条件下稳定的铀固定化。该项目期望产生关于铀形态和稳定性与基质矿物、微生物区系和环境条件之间关系的新知识。该项目的预期成果包括优先将铀固定到耐空气和耐酸的稳定物种的新战略。该项目的预期效益包括减轻铀污染和促进澳大利亚铀业的可持续发展。

This project aims to reveal the mechanisms of uranium transformation and immobilisation in both aerobic and anaerobic conditions of bioremediation with the emphasis on elucidating stable uranium immobilised under different pathways and conditions. This project expects to generate new knowledge regarding the relationship between uranium speciation and stability with the matrix mineral, microbiota, and environmental conditions. Expected outcomes from this project include new strategies for preferential immobilisation of uranium to stable species that are resistant to air and acid. The anticipated benefits of this project include mitigating uranium contamination and promoting the sustainable development of the uranium industry in Australia.
