a simple, fast and one-pot synthesis procedure based on the bioreduction ability of an algal extract solution has been developed to produce silver nanoparticles (agnps). we focus especially on the influencing factors of agnps formation. the effects of various factors like ph, temperature, the concentration of metal ions and alga, the volume ratio of silver nitrate solution to alga extract, reac...

In this article, we used Sargassum hystrix algae as biosorbent for removal of Fe (II) from aqueous solutions that was collected along the Persian Gulf coastline, Bushehr, Iran. The concentration level of remaining Fe (II) in the samples was measured by using flame atomic absorption spectrometry (FAAS, Varian AA240, Australia). The isotherms, kinetics and modeling data of Fe (II) biosorption ont...

The effect of Sargassum pallidum (brown seaweed) aqueous extract on the immunity function and antioxidant activities in was studied gastric cancer rats. Treatment with Sargassum pallidum aqueous extract at oral doses 400, 600 or 800 mg/kg body weight was found to provide a dose-dependent protection against N-methyl-N′-nitro-Nnitrosoguanidine (MNNG)-induced immunity damage and oxidative injury b...

In order to investigate the behavior of rare earth elements (REEs) and uranium (U) in marine organism, the concentrations of REEs and U in some brown algae samples taken on the coast of Niigata Prefecture were determined. In addition, laboratory model experiment to uptake these elements using living and dried algae (Undaria pinnatifida and Sargassum hemiphyllum) was also carried out to survey t...

The chemical compositions, antioxidant and antimicrobial properties of fucoidan extracted from Sargassum ilicifolium and S.angustifolium were investigated. The results showed that these seaweeds were characterized by an acceptable level of minerals and proteins. The fatty acid profile was dominated by the palmitic acid, which represents about 37.44±0.01% and 23.05±0.01% of the total fatty acids...

Sargassum kendrickii N. Goldberg et Huisman, sp. nov. is described from subtidal habitats in the Esperance region, southern Western Australia. The new species belongs to the subgenus Phyllotrichia and can be distinguished from all previously described species in the morphology of its lateral branches, which are pinnate, alternately arranged, and have serrated margins. Vesicles are absent and re...

the seaweeds like sargassum ilicifolum arecan used for animal nutrition. the aim of this study was evaluated the nutritional value of sargassum ilicifolum as a food supplement in the diet of sheep. in this experiment were five diets containing zero, 10, 20, 30 and 40 percent of the seaweed were used. a completely randomized design was used to this purpose. in this study, the chemical compositio...
