Microbially enabled carbonate mineral precipitation in natural and engineered environments
The research focuses on the role microorganisms play in accelerating the formation of calcium and magnesium carbonate minerals in a variety of natural and engineered environments. In reef sand cay environments, microbially enabled cement formation can aid the consolidation of beach sediments, increasing the stability of islands in the Great Barrier Reef. The stabilisation properties of these carbonate cements also have applications to the rehabilitation of modern and historic mine sites. Jenine is studying how carbonate cements can be used to immobilise hazardous asbestos mine tailings, while also sequestering atmospheric carbon dioxide in the tailings.
