Overview of fungal bioleaching of metals
M e O is a metal oxide such as NiO (Nickel(II) oxide), Fe 2 O 3 (Ferric oxide), and the same reaction also applies to CaCO 3 (Calcium carbonate) Example of acid leaching reaction. 3.2. Complexolysis. Complexolysis is accomplished through the chelation mechanism, thereby balancing the metal ions from the solution by acidolysis.

Understanding the pathway of antibacterial activity of copper oxide
This work investigates the role of oxidation state in the antibacterial activity of copper oxide nanoparticles (NPs). The findings add strong support to a contact killing mechanism of copper oxides (CuO and Cu 2 O) through which bacteria initially suffer severe damage to the cell envelope. Then further damage ensues by an independent …
