Hydrothermal extraction of ulvans from Ulva spp. in a biorefinery approach [PDF]

Science of the Total Environment
A simple cascade process based on the hydrothermal fractionation of Ulva spp. biomass was proposed. Considering the overall extraction yields (50 %), ulvan recovery (23 %), and ulvan composition, structural, mechanical and cytotoxic properties, the selected optimal final heating temperature was 160 °C.

Anti-inflammatory potential of ulvan [PDF]

International Journal of Biological Macromolecules, 2023
Green seaweeds are a widespread group of marine macroalgae that could be regarded as biorenewable source of valuable compounds, in particular sulfated polysaccharides like ulvans with interesting biological properties. Among them, anti-inflammatory activity represents an interesting target, since ulvans could potentially avoid side effects of ...
