Antimicrobial Activity of the Marine Algal Extracts against Selected Pathogens
The inhibitory effect of <em>Ulva lactuca</em> (Chlorophyta), <em>Dilophus spiralis </em>(Phaeophyta) and <em>Janiarubens </em>(Rhodophyta) marine algae species has been evaluated against 2 Gram-positive bacterial (<em>Streptococcus pyogenes</em> and<em> Micrococcus luteus</em>); 2 Gram-negative bacterial (<em>Shigella flexneri</em> and<em> Vibrio cholerae</em>) and 2 fungal (<em>Candida albicans</em> and <em>Aspergillus niger</em>) isolates using aqueous and six organic extracts (methanol, ethanol, chloroform, acetone, ethyl acetate and hexane). Data revealed that the <em>M. luteus</em>bacteria was the most sensitive pathogen by showing the highest zone of inhibitions (ZIs) of 17 mm with the lowest Minimum Inhibitory Concentration (MIC) of 26.7 µgmL<sup>-1</sup> and the lowest Minimum Bactericidal Concentration (MBC) of 53.3 µg mL<sup>-1 </sup>with chloroform <em>D. spiralis</em> extract. Whereas, aqueous extracts were not active against all selected pathogens regardless of the examined algae species. Based upon data presented herein, chloroform <em>D. spiralis </em>extract was the most active against examined pathogens. Thereby, future performance research in <em>D. spiralis</em>is requested due to their high effectiveness as a cheap antimicrobial agent.
