| Popis: | The anticorrosive and antifouling properties of the Gracilaria edulis extract (1%, w/v) incorporated epoxy paint have been evaluated in the Gulf of Mannar Coast, Mandapam, India for an year. The antibacterial activity of G. edulis extract was determined by disc diffusion method and minimum inhibitory concentration against 5 bacterial isolates by Broth Macro dilution method using Mueller Hinton broth. The anticorrosive property of the G. edulis extract was studied by Salt spray test and electrochemical impedance measurements. The extract was characterized by FTIR, NMR and atomic absorption spectrometer. Laboratory tests reveal the antibacterial and anticorrosive properties of the extract. G. edulis extract incorporated epoxy based paint exhibited both anticorrosive and antifouling properties in natural seawater for 6 months. |
