Abstract
Seaweeds are macroscopic algae growing in the environments like marine and shallow coastal waters and on rocky shores. The major industrial products of seaweeds are as a source of agar, agarose and carrageenan. Seaweeds contains various pharmacologically important bioactive compounds like carotenoids, flavonoids, fibre, protein, essential fatty acids, vitamins and minerals. The present study mainly focus with the analysis of elemental composition of five species of red seaweeds (Rhodophyceae) and five species of brown seaweeds (Phaeophyceae) using SEM-EDS. The collected seaweed species were washed, shade dried and then grinded into a fine powder. The elements present in the seaweed species were determined by SEM-EDS in central instrumentation laboratory, Department of physics, Annamalai University. Various elements present in the seaweeds are N>Na>Mg>Al>Si>Cl>S>B>K>Ca>Mn>Fe>Cu>Zn. Among these various elements in all seaweeds, maximum amount of nitrogen and potassium are observed in the Gracilaria corticata and Sargassum wightii followed by Kappaphycus alverzii and Turbinaria ornata. Based on the results, the Gracilaria corticata and Sargassum wightii can be used as a liquid fertilizer, which will improve the crop growth and productivity and hence these two seaweeds namely Gracilaria corticata and Sargassum wightii are analysed for further studies.
