Haloalkaliphilic sulphur oxidising bacteria in dealkalising bauxite residue

本项目旨在通过对硫氧化细菌的分类组成和分子代谢的新认识，建立中和铝土矿冶炼废物的突破性技术，这些细菌能够在极卤碱性生态位中氧化低成本元素硫。研究结果将与工业伙伴合作，转化为实地可行的生态工程技术。DECRA项目还将为澳大利亚的净零废物战略做出贡献，如果实施，可能会对采矿废物、碳排放和土壤枯竭等全球问题做出重大贡献。技术方案的商业化将增加澳大利亚的经济优势和就业。

This project aims to establish breakthrough technology for neutralising bauxite refinery wastes by creating new knowledge about the taxonomic composition and molecular metabolism of sulphur oxidising bacteria capable of oxidising low-cost element sulphur in extremely haloalkaline niches. The findings will be translated into field feasible ecological engineering technology in partnership with industry partners. This DECRA project will also contribute to the net zero waste strategy in Australia and could significantly contribute to global problems of mining waste, carbon emission, and soil depletion if implemented. The commercialisation of the technology package will increase economic advantages and employment in Australia.
