Researchers show how bacteria convert toxic copper ions to stable metallic copper
Researchers from the University of Houston, with colleagues at the University of São Paolo in Brazil, have demonstrated how copper-resistant bacterium from a copper mine in Brazil convert CuSO
4 (copper sulfate) ions into zero-valent Cu (metallic copper). An open-access paper on their research is published in
Science Advances.
et al.
The idea of having bacteria in mines is not new, but the unanswered question was: what are they doing in the mines? By putting the bacteria inside an electronic microscope, we were able to figure out the physics and analyze it. We found out the bacteria were isolating single atom copper. In terms of chemistry, this is extremely difficult to derive. Typically, harsh chemicals are used in order to produce single atoms of any element. This bacterium is creating it naturally that is very impressive.

Mehmet Orman, assistant professor of chemical and biomolecular engineering at the University of Houston Cullen College of Engineering, has received a Faculty Early Career Development (CAREER) Award from the National Science Foundation. NSF CAREER awards are granted to highly promising junior faculty members who exemplify the role of teacher-scholars through outstanding research, excellent education and the integration of education and research.
The CAREER award will provide Orman with $500,000 to study so-called persister cells - those that go dormant and then become tolerant to extraordinary levels of antibiotics.
