Posidonia oceanica waste biomass has been valorised to produce extracts by means of
different methodologies and their bioactive properties have been evaluated. Water-based extracts
were produced using ultrasound-assisted and hot water methods and classified according to their
ethanol-affinity (E1: ethanol soluble; E2: non-soluble). Moreover, a conventional protocol with organic
solvents was applied, yielding E3 extracts. Compositional and structural characterization confirmed
that while E1 and E3 extracts were mainly composed of minerals and lipids, respectively, E2 extracts
were a mixture of minerals, proteins and carbohydrates. All the extracts showed remarkably high
antioxidant capacity, which was not only related to phenolic compounds but also to the presence of
proteins and polysaccharides. All E2 and E3 extracts inhibited the growth of several foodborne fungi,
while only E3 extracts decreased substantially the infectivity of feline calicivirus and murine norovirus.
These results show the potential of P. oceanica waste biomass for the production of bioactive extracts.
