Extensive variations in diurnal growth patterns and metabolism amongst Ulva spp strains
• Ulva spp. possess unique diurnal growth pattern and primary metabolism, with higher growth rates during the night than during the light period;
• Large variability in growth and metabolism among morphologically similar Ulva spp. strains;
• Strain selection justified to increase biomass, metabolite yields and nutrient removal in aquaculture industry.

Lipidomic signature of the green macroalgae Ulva rigida farmed in a sustainable integrated multi-trophic aquaculture
• Investigates the lipid profile of Ulva rigida produced in a land-based integrated multi-trophic aquaculture (IMTA) system using liquid chromatography coupled to high-resolution mass spectrometry for molecular lipid species identification;
• The lipidome of U. rigida revealed the presence of distinct beneficial n-3 fatty acids for human health, namely alpha-linoleic acid (ALA) and docosapentaenoic acid (DPA);
• Contributes to the valorization and quality validation of sustainably farmed U. rigida.

Magnetic beads, a particularly effective novel method for extraction of NGS-ready DNA from macroalgae
• Magnetic bead extraction is an efficient method to obtain DNA from macroalgae;
• It yields better DNA quality and quantity versus with column-based kits and CTAB;
• Generation of RAD-Seq data from 12 Ulva samples;
• RAD-Seq data on Ulva species allows for high discriminatory power versus barcoding.
