Última Effects of iron-ore particles on propagule release, growth and photosynthetic performance of Sargassum vulgare C. Agardh (Phaeophyta, Fucales) Rev. Bras. Bot. NASSAR,CRISTINA A.G.; LAVRADO,HELENA P.; YONESHIGUE-VALENTIN,YOCIE. The effect of iron-ore particles on the propagule release and growth of Sargassum vulgare C. Agardh was tested under treatments with different concentrations of iron-ore particles: 0.1, 1.0, 10.0 g.L-1 and a solution of 10.0 g.L-1 of filtered iron-ore. Filtered seawater was used as control. Photosynthesis vs. irradiance (P-I) curves were calculated for S. vulgare in the presence of iron-ore and in seawater. There was no significant difference in the number of propagules released by the receptacles or in the percentage of zygote formation among the treatments. The released propagules acted like aggregation centers for the particles, those more heavily coated with iron (10.0 g.L-1) exhibiting the highest sinking velocity (32.6 ± 9.8 mm.s-1). No difference in... Tipo: Info:eu-repo/semantics/article Palavras-chave: Growth; Iron-ore; Macroalgae; Net photosynthesis; Sargassum vulgare. Ano: 2002 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-84042002012000010 Glycoglycerolipids From Sargassum vulgare as Potential Antifouling Agents ArchiMer Plouguerné, Erwan; De Souza, Lauro M.; Sassaki, Guilherme L.; Hellio, Claire; Trepos, Rozenn; Da Gama, Bernardo A. P.; Pereira, Renato Crespo; Barreto-bergter, Eliana. Unraveling new environmentally friendly antifouling (AF) agents is one of the major quests currently facing marine biotechnology. Marine macroalgae represent a rich source of new compounds with promising biological properties, including AF activity, but most of the macroalgal compounds studied to date are terpenoids or polyphenolics. The aim of this work was to investigate the possible AF role played by a usually neglected class of marine natural products: glycolipids (monogalactosyldiacylglycerols – MGDG, digalactosyldiacylglycerols – DGDG and sulfoquinovosyldiacylglycerols – SQDG) isolated from the Phaeophyceae Sargassum vulgare collected along the coast of south-eastern Brazil. Among the 18 extracts, fractions and sub-fractions tested, 3 sub-fractions... Tipo: Text Palavras-chave: Sargassum vulgare; Glycoglycerolipids; Antifouling; Microfouling; Macroalgae.
