| contents | Bioprospecting seaweed derived bio-oil as a marine biofouling mitigating agent. Gopinathan, Sainath Krishnan, Srividhya Jothipandiyan, Sowndarya Sivaraman, Subramaniyasharma Satish, Lakkakula Venkatachalam, Ponnusami Ramiah Shanmugam, Saravanan Paramasivam, Nithyanand Biofouling Biofilms Seaweed Bioprospecting Paint Oils Gas Chromatography-Mass Spectrometry Bacterial Adhesion Extracellular Polymeric Substance Matrix Mitigating marine biofouling using marine resources has become a research hotspot as it is considered an environmentally friendly approach. Hence, this study investigated the biofilm mitigating property and antifouling activity of bio-oil extracted from the pyrolysis of seaweed biomass. The bio-oil inhibited up to 73-80% of biofilm and extracellular polymeric substance (EPS) formation of the predominant marine microfoulers , and . Gas chromatography-mass spectrometry (GC-MS) analysis of the bio-oil identified that 13-Docosenamide () is a prominent compound that accounts for about 27.42% of the total bio-oil composition which might be responsible for its antibiofilm property. The bio-oil was further formulated into antifouling paint equivalent to the consistency of traditional antifouling paints and coated on titanium plates. The water contact angle results showed that bio-oil and antifouling paint exhibit hydrophilic surfaces, effectively reducing bacterial attachment. Scanning electron microscopic analysis revealed that the anti-fouling paint coated on titanium plates against mixed species of microfoulers significantly reduced biofilms. Molecular docking of 13-Docosenamide () against the mussel adhesive foot protein of (Pvfp-5b) exhibited favorable binding scores, indicating that it may reduce the bio-adhesion of macrofoulers to the substrate. |
