DESCRIPTION:Earth’s geosphere and biosphere have coevolved over time\, i
 nfluencing each other’s stability and keeping our planet habitable over 
 the last ~4 billion years. Biogeochemical cycles play a key role in contro
 lling this interaction\, connecting long-term geological cycles and the mu
 ch faster evolution of the Earth’s outer biologically dominated envelope
 s. A small set of microbial-encoded proteins containing redox-sensitive tr
 ansition metals as their core catalytic center carry out the majority of t
 he key biogeochemical reactions. Metals such as Fe\, Co\, Ni\, Zn\, Mo\, W
 \, V\, and Cu are used in these proteins to access diverse redox couples a
 s a function of the changing planetary availability of these elements over
  time. Despite the importance of this process\, the relationship between m
 etal availability and metabolism evolution and diversity has not been inve
 stigated in detail. Here\, we will present recent data from field and labo
 ratory experiments elucidating the impact of transition metal availability
  on microbial functional diversity\, and its implications for the emergenc
 e and evolution of life on Earth\, while discussing the implications of th
 ese findings for the search for life in the Universe.\nSpeakers:\nProf Don
 ato Giovannelli (University of Naples “Federico II”)
