Caption: BIOMINERALIZATION OF Fe OXIDES AND ZnS AT THE TENNYSON MINE, WI
"This is a new project that explores the process of biologically-induced precipitation and growth of Fe-hydroxides, oxyhydroxides, and oxides by microaerophilic bacteria and of ZnS (sphalerite) by sulfate-reducing bacteria under anoxic natural conditions. Other research focuses on the nucleation and growth of clay mineral products of biomineralization.This work overlaps directly with our work on nanocrystalline materials"
