Implication

Experimental study demonstrates reduced biofilm formation and macrofouling with sea urchin and mangrove extracts, suggesting their viability as eco-friendly antifouling coatings.

Key Points

To assess the antifouling efficacy of Diadema setosum and Sonneratia lanceolata crude extracts in coatings and identify their active secondary metabolites.
Screened crude extracts for in vitro biofilm inhibition against Pseudomonas aeruginosa using crystal violet assays.
Formulated marine paints with 5% and 10% (w/v) extracts for aquarium bacterial tests and open-water submersion testing in Kemaman and Pulau Redang, Malaysia.
Identified bioactive secondary metabolites within the crude extracts using liquid chromatography-mass spectrometry (LC-MS).
Both crude extracts inhibited Pseudomonas aeruginosa biofilm formation, with the 5% S. lanceolata formulation exhibiting the highest inhibition of natural seawater bacteria in aquarium tests.
Paint formulations containing crude extracts reduced macroorganism settlement and macroalgae growth relative to blank paint during seawater submersion.
LC-MS characterization revealed active compounds including 3-methyloxiranyl phosphonic acid in S. lanceolata, as well as 8-decene-1,3,5-triol and 3-hydroxyundecanoic acid in D. setosum.
