In this study, the antibiofilm and antioxidant activities of the crustose coralline alga (CCA)Lithophyllum sp. collected from the central Red sea was investigated. The dried CCA samples were extractedwith hot water and methanol. Both extracts were tested against marine biofilm forming bacteria to assess theantibiofilm activity. Results showed that methanol extract of the CCA inhibited bacterial growthconsiderably. The water extract revealed higher antioxidant activity than the methanol extract. The FT-IRspectrum of the CCA showed the presence of functional groups like alkanes, alcohol, carboxylic acid, ethersand esters. In general, results of the present study indicated that CCA produces bioactive compounds, whichcan inhibit the attachment of unwanted marine bacteria on their surfaces.
