The aim of the present study was to screening of the eco-friendly anti-biofilm antimicrobial compound from marine seaweeds, characterization of the bioactive metabolites though FTIR. Method Confirmation of biofilm activity was evaluated using Congo red agar method where the organisms where streaked over Congo red agar method, Results The different parameters namely morphological, biochemical testes have been used for characterization and identification of marine biofilm bacteria Conclusion Anti- biofilm metabolites assess from the above results indicates the presence of active constituents in the extractions of natural plants of seaweeds which showed better antimicrobial activity against micro-fouling bacteria.
