Abstract
This study aims to investigate the effect of some algal extracts as antibacterial agents against some pathogenic bacteria. Thus the ethyl acetate and methanolic extracts of the marine algae Ulvalactuca, Enteromorphacompressa, Ulvafasciata, Pterocladiacapillacea, Corallinamediterranea, Hypneamusciformis and Padinapavonia, collected from the coast of Alexandria (Egypt), were tested as antibacterial agents against fish and human pathogenic bacteria; Aeromonashydrophila, Vibrioanguillarum, Pseudomonasfluorescens, Staphylococcusaureus, Pseudomonasaeruginosa and Salmonellatyphimurium. The best activities were shown by the methanolic-L extract of P. capillacea against P.fluorescens, V.anguillarum and P.aeruginosa. The methanolic-L extract of U. lactuca showed high activity towards A. hydrophila, V. anguillarum, P. fluorescens and S. aureus. Cluster analysis was used to study the action of the crude algal extracts.
