Marine algae are known to produce a wide variety of bioactive secondary metabolites and several compounds have been derived from them for prospective development of novel drugs by the pharmaceutical industries.
However algae of the Red sea have not been adequately explored for their potential as a source of bioactive substances.
In this context Ulva reticulata, Caulerpa occidentalis, Cladophora socialis, Dictyota ciliolata, and Gracilaria dendroides isolated from Red sea coastal waters of Jeddah, Saudi Arabia, were evaluated for their potential for bioactivity.
Extracts of the algae selected for the study were prepared using ethanol, chloroform, petroleum ether and water, and assayed for antibacterial activity against Escherichia coli ATCC 25322, Pseudomonas aeruginosa ATCC 27853, Stapylococcus aureus ATCC 29213, and Enterococcus faecalis ATCC 29212.
It was found that chloroform was most effective followed by ethanol, petroleum ether and water for the preparation of algal extract with significant antibacterial activities, respectively.
Results also indicated that the extracts of red alga G.
dendroides were more efficient against the tested bacterial strains followed by green alga U.
reticulata, and brown algae D.
ciliolata.
Chemical analyses showed that G.
dendroides recorded the highest percentages of the total fats and total proteins, followed by U.
reticulata, and D.
ciliolate.
Among the bioflavonoids determined Rutin, Quercetin and Kaempherol were present in high percentages in G.
dendroides, U.
reticulata, and D.
ciliolate.
Estimation of saturated and unsaturated fatty acids revealed that palmitic acid was present in highest percentage in all the algal species analyzed.
Amino acid analyses indicated the presence of free amino acids in moderate contents in all the species of algae.
The results indicated scope for utilizing these algae as a source of antibacterial substances.
