The journey begins

Bacteria exploit metals in a clever way for metabolic purposes, to generate energy, and to produce biominerals. When metals are toxic, bacteria have developed sophisticated strategies to counteract them. Our team focuses on unraveling the complex interaction between bacteria and metals looking at several key aspects such as biomineralization and anaerobic respiration based on “exotic” elements. An additional research direction aims at recovering secondary resources from industrial effluents (“circular economy”) using microbial metabolism or the chemistry of such complex systems.

There is grandeur in this view of life, with its several powers, having been originally breathed by the Creator into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.
― Charles Darwin, The Origin of Species (1859)
