Abstract: Marine biofilms formed by bacteria and other microorganisms adhering to underwater surfaces are usually considered to be the main form of micro pollution. Subsequently, the larvae of barnacles, mussels and other higher organisms attached to the marine biofilm, resulting in macro pollution. Several methods can be used to prevent micro and macro pollution. Silver nanoparticles (AGNPS) have strong inhibitory and antibacterial activities. The biosynthesis of AgNPs has received rapid attention because of its increasing success. Therefore, the focus of this study is to study the biosynthesis and characteristics of AgNPs from the fruit extract of Suzuki by UV-Vis spectrophotometer, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and atomic force analysisicroscopy (AFM). Further isolation and identification of marine biofilm forming bacteria were carried out through 16S rDNA analysis. The antimicrofouling effect of the biosynthesized AgNPs was tested against marine biofilm forming bacteria and the results suggested that it could effectively inhibit biofilm formation. This preliminary study has proved that AgNPs may be used as antimicrofouling agent for the prevention of biofouling in the early stages.
