Macrophytes represent interesting matrices for oil extraction with biodiesel production purposes, particularly in eutrophic coastal lagoons. This short note reported results on bio-oil extraction efficiency in two different species of macrophytes in a Mediterranean lagoon (Lesina lagoon, south-eastern Italy), by testing effects of different factors (year, season, species of macrophytes) on oil production and oil quality. Extracted total oils values ranged from 0.65 % (Chara spp.) to 2.35 % (Chaetomorpha linum) and a significant difference (p < 0. 01) between the two species was reported in relation to the variability of diene production with seasons. Compared to the available literature, higher oil extraction efficiencies are reported in this paper for the species C. linum, mainly due to the pressure optimization before extractions.

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.
