N2 - Microfouling is evolving at a fast rate causing augmented mortality rates and damage worldwide. Until now, several remedial measures have been exploited to overcome microfouling, amongst them nanoparticles play a superior role. Currently, green synthesized nanoparticles have been centered owing to its eco-friendly, cost effectively and non-toxic nature which has also increased its industrial applications (biomedicine, food and textile). In the present research Silver Nanoparticles (Ag NPs) synthesized using marine red algae Gelidium amansii. The synthesized Ag NPs were characterized using UV-Vis Spectroscopy, Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM). Further the antibacterial potentials of Ag NPs were evaluated against pathogenic Gram positive (Staphylococcus aureus, Bacillus pumilus) and Gram negative bacterial (Escherichia coli, Pseudomonas aeruginosa, Vibrio parahaemolyticus, Aeromonas hydrophila) pathogens. Our findings suggest that Ag NPs synthesized using a green approach effectively reduce the bacterial growth by eliciting a bactericidal activity against the Gram Negative and Gram Positive biofilm forming pathogens. Thereby, Ag NPs synthesized using G. amansii could reflect as potential anti micro-fouling coatings for various biomedical and environmental applications.
