Characterization and Evaluation of Copper and Nickel Biosorption on Acidic Algae Sargassum Filipendula. However, this method has some drawbacks such as low yield and toxic. The filtered solution taken as dye and the same was used for our present study. New York: John Wiley & Sons; 1996. Comparative study of the equilibrium of different metallic ions by the marine alga Sargassum filipendula and by the extracted alginate. Sargassum valorization has become increasingly important as the Caribbean region continues to struggle with the massive growth of the seaweed and its damaging effects. Initially, a comparison between the spectra obtained for marine alga S. filipendula and the alginate biopolymer extracted from this alga was performed. PMid:15158390. http://dx.doi.org/10.1016/j.jcis.2004.01.036        [ Links ], Figueira MM, Volesky B and Matheus HJ. Several studies point out the high efficiency of different species of the marine alga Sargassum in the bioadsorption of different metallic ions, many of these using Brazilian Sargassum sp.6-9 No studies were found using alginate extracted from Brazilian algae for application as bioadsorbent. The dry alga was soaked in formaldehyde 0.4% for 30 minutes, rinsed with water and dropped into a HCl solution (0.1 mol.L–1) for 2 hours. FAO Fisheries Technical Papers. the use of extraction, to allow the direct transformation of the mixed salts (Na+, Mg+2+, and Ca2+) of alginate into . Potential Uses: None Found . Design Expert 10.0.3 was used to formulate the experimental methodology, and to coordinate optimization through statistical verification. Production, properties and uses of Alginates. PMid:16797834. http://dx.doi.org/10.1016/j.jhazmat.2006.05.017        [ Links ], Kleinübing SJ, Guibal E, Da Silva EA and Da Silva MGC. Sujata Sahoo .

Seaweed Extract. Sargassumsp. Consequently, a greater resistance to mass transfer and an increase in the time needed to reach adsorption equilibrium could be noticed for the alginate biopolymer. alginates has arisen [11,12]. Chemosphere. Sargassum oligocystum with variations being dependent on the alginate extraction method used. With the results obtained, it was possible to conclude that the marine alga S. filipendula adsorbs the metallic ions in a different manner. 3. London: Academic Press; 1967. p. 219. (ii) The seaweed was mixed with distilled water approximately 1:3 ratios respectively were heated for 3 hrs at 80 ̊C. carried out by the maceration method. The alginate beads were kept in contact with calcium chloride for 24 hours. Different extraction techniques have been used to maximize biologically active compounds isolation from plant material , for ... Sivasangari et al. Bioadsorption studies with marine alga Sargassum sp. The relationship between molecular structure and bioactivity was evaluated for alginates obtained under different extraction methods (water, acid, alcalase and cellulase) from Sargassum angustifolium. This technique offers excellent information on the nature of the present bands, allowing the identification of different functionalities on the cellular surface. Materials and Methods: To explore the effect of Sargassum wightii on calcium oxalate crystallization, in vitro assays like crystal nucleation, aggregation and crystal growth were performed. study was to systematically evaluate the phlorotannin rich extract of Sargassum wi-ghtii using suitable in vitro and in vivo models to provide scientific evidence for its antilithiatic activity. The solution was then dripped into an aqueous solution of calcium chloride at 4% (CaCl2.2H2O, Nuclear brand). The isolated study of this biopolymer as a bioadsorbent might aid the understanding of the mechanisms involved in the bioadsorption process of different metallic ions by the marine alga. An alternative Differences in molecular conformation between M and G blocks are the main responsible for the variation in alginate affinity for metallic ions4,5. Advances in Carbohydrate Chemistry and Biochemistry. Seaweeds are one of the types of macroscopic biomass known for their metal-sorbing potential. Boca Raton: CRC Press, Inc.; 1983. Characterization of the bleached alginate through NMR studies validated with FTIR, gave an M/G ratio of 0.45 with a molecular weight of 3.14 × 105 g mol−1 and viscosity of 14.10 cP aligned to high gelling capabilities. via spectroscopic and modeling analysis. In addition, fucoidans extracted from the cell wall were discovered to have antitumor [2] and cytotoxic activities [3]. Chemistry and Enzymology of Marine Algal Polysaccharides. 2006; 22:8906-8914. 26 Nov 2015. Correspondingly, covalent binding was more important for Cu than for Ni, which was bound predominantly by electrostatic attraction. 2006; 792-793:104-109. http://dx.doi.org/10.1016/j.molstruc.2005.12.053        [ Links ], Chen JP and Yang L. Study of a heavy metal biosorption onto raw and chemically modified Sargassum sp. The method described by Mchugh11 was used for extracting the alginate. Crude fucoidan on the best conditions was composed by oligosaccharides … Band shifting provides an indication of the functional group interaction with metallic ions. By continuing you agree to the use of cookies. The alginate is extracted from the alga in the form of sodium alginate, and in order to be used as bioadsorbent, it is jellified in the form of calcium alginate. 2.5. Sargassum, also called gulfweed or sea holly, genus of about 150 species of brown algae (family Sargassaceae) generally attached to rocks along coasts in temperate regions or occurring as pelagic (free-floating) algae in the open sea.
