Synthetic description of the research activity

Research activity in Marine Microbial Ecology.

Research activity focuses on the synecological and physiological study of planktonic Bacteria and Archaea in the North Adriatic coastal and paralic systems, in particular on the role played by these organisms in organic matter production, utilization and degradation. 

Studies on the ecophysiology of Antarctic bacterial strains isolated in the Ross Sea, aimed to evaluate the role of such prokaryotes on organic matter degradation/utilization and carbon dioxide production have been performed.

Subsequently, researches have focussed on the qualitative composition of bacterioplankton communities through molecular biology analytical methods. Several studies have been carried out in order to depict spatial and temporal variability of prokaryotic communities in different environments (from the Southern Ocean, through the Mediterranean to the Arctic Ocean) and their link to degradation and production processes in pelagic and benthic systems.

More recently researches are focussing on the effect of increased CO2 in the marine environment on diversity and functionality of planktonic and benthic microbial assemblages.

In the last years investigations on deep-sea prokaryotic metabolism (heterotrophic production, dissolved inorganic carbon fixation, respiration) have been carried out in the Mediterranean Sea, in the Ross Sea and in the Barents Sea.
