The phylum Porifera and their symbionts produce a wide variety of bioactive compounds, playing a central role in their ecology and evolution. In this study, four different extracts (obtained by non-polar and semi-polar extraction methodologies) of the Mediterranean sponge
Ircinia oros
were tested through a multi-bioassay integrated approach to assess their antifouling potential. Tests were performed using three common species, associated with three different endpoints: the marine bacterium
Aliivibrio fischeri
(inhibition of bioluminescence), the marine diatom
Phaeodactylum tricornutum
(inhibition of growth), and different development stages of the brackish water serpulid
Ficopomatus enigmaticus
(gametes: sperm motion, vitality inhibition and cellular damage; larvae: development; adults: AChE (acetylcholinesterase)-inhibitory activity). The effects of extracts were species specific and did not vary among different extraction methodologies. In particular, no significant reduction of bioluminescence of
A. fischeri
was observed for all tested samples. By contrast, extracts inhibited
P. tricornutum
growth and had toxic effects on different
F. enigmaticus
’ developmental stages. Our results suggest that the proposed test battery can be considered a suitable tool as bioactivity screening of marine natural products.
