In order to understand bacterial-phytoplankton interactions in harbor environments, trophic conditions (nutrient, chlorophyll, organic matter), microbial enzyme activities and phytoplankton dynamics were studied seasonally from September 2018 to August 2019 in the Syracuse Gulf (Ionian Sea), a Mediterranean area subject to algal blooms. During spring, dinoflagellate bloom was coupled with high microbial activity rates; these actively recycled nutrients, sustaining phytoplankton growth.

Research Projects

The research activities of the Institute are carried out in the context of research, development and innovation projects, both national and international, based on regional funding programs (POR FEAMPA - Regional Operational Program of the European Maritime Affairs Fisheries Fund and Aquaculture and POR FESR - Regional Operational Program of the European Regional Development Fund) or ministerial (PRIN - Projects of relevant national interest, PNRA - National Research Program in Antarctica, PO FEAMPA - National Operational Program European Maritime Affairs Fisheries and Aquaculture Fund) , programs for European Territorial Cooperation (Interreg), direct funding programs of the European Commission (Horizon2020 and Horizon Europe, Life, JPI - Joint Programming Initiatives, ERA-NET Cofund) and thematic collaboration initiatives managed by international organizations such as, for example , the FAO - GFCM (General Fisheries Commission for the Mediterranean). The Institute also develops funded projects in the context of collaborations with private companies in the sectors of the blue economy as well as technology transfer and research results. Research projects, mainly of a collaborative nature, are developed through a wide network of partners that include major Italian and foreign research institutions and universities.
