23/04/2021Here, we discovered an environmental bacterium found in a copper mine that can synthesize single atoms of Cu 0 in a sustainable manner. Its biosynthetic mechanism was proposed using the proteomics approach. This sustainable synthesis of Cu 0 is carried out in microbial growth media, eliminating the use of toxic solvents.

26/09/2019Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0% copper. The refining techniques employed by copper producers depend on the ore type, as well as other economic and environmental factors. Currently, about 80% of global copper production is extracted from sulfide sources.
