Haloalkaliphilic sulphur oxidising bacteria in dealkalising bauxite residue

点击翻译按钮获取中文摘要

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.
