Hurtado-Ponce AQ, Umezaki I. mass quantities of sargassum seaweed) in the Caribbean region; and, importantly, by offering guidance on how best to sustainably manage the seaweed, based on lessons learnt to date. The marine brown alga Sargassum sub-repandum (Forsk) was collected fromRas Gharib in the Egyptian Red Sea coast. Sargassum brown seaweed is known to have many health benefits and therapeutic effects. However, those conducting the other half of the project - biomass conversion to methane by anaerobic fermentation - found that Sargassum gave a poor gas yield. The solvent was filtered off and the seaweed washed with distilled water, then allowed to dry in the sun. 2004. Fucoidan is a polysaccharide with high sulfate content, found in the cell walls matrix of brown seaweed. Most species within the class Phaeophyceae are predominantly cold-water organisms that benefit from nutrients upwelling, but the genus Sargassum appears to be an exception. This study aimed to evaluate chemical composition … The Sargassum seaweed plague is increasingly affecting coastal areas in the Caribbean region causing wide spread economic and ecologic damage. constituents and biochemical composition of this alga have never been reported. In addition, the biological activity (antioxidant and antibacterial) of the ethanolic extract and anticoagulant activity of the fucoidan were examined. For instance, higher water temperature has a positive correlation with CDOM production. Sargassum binderi Sonder obtained from Binuangeun (Banten), Indonesia which has not been reported so far. The sargassum mats near shore had prevented light from reaching the seabed, created anoxic conditions, and leached nutrients (Mar Pollut Bull, 122:272–81, 2017).The seagrass meadows had changed composition, too, from being dominated by a species that stabilized the sediment with its robust rhizome network to a type of grass that allowed for greater erosion. All figures, except for water (as percentage), are given as grams per 100 grams of dry matter. Manivannan et al. The tourist sector is hit hard and complete bays included corals and other sealife are destructed by layers of sinking and rotting seaweed. The proximate composition was investigated The chemical destroys electronics.” As the founder and managing Fatty acid (FA) composition covered the branched chain C13ai to C22:5 n3 with variable content in n6 and n3 FA; low n6:n3 ratios were observed in O. pinnatifida, Grateloupia turuturu and C. tomentosum. Earlier work on Sargassum exudation (Shank et al 2010) supports this finding and highlights environmental variations on exudation rates due to the length of incubation, light and temperature variations. Biosorption of cadmium by brown, green, and red seaweeds. The phytochemical screening, nutritional composition and bioactive potential of Sargassum polycystum (Brown Seaweed) were investigated. Composition (%) Ash 17.74 ± 1.24 Moisture 4.82 ± 0.84 Protein 8.69 ± 0.46 Lipid 0.81 ± 0.17 Carbohydrate 62.78 ± 1.21 All results expressed as means ± SE, based on triplicated trials. Numerous species are distributed throughout the temperate and tropical oceansof the world, where they generally inhabit shallow water and coral reefs, and the genus is widely known for its planktonic (free-floating) species. He told OBSERVER AM yesterday that this was happening “because decomposing sargassum seaweed emits hydrogen sulfide into the air. Sargassum muticum Wireweed What is it? The Material The raw material used in this work was obtained from a brown seaweed Sargassum binderi Sonder collected from Binuangeun. The table below gives the chemical composition of selected, representative seaweeds, some of which are currently used for food or have been used as food in the past. Nutritional composition analysis of seaweed Sargassum crassifolium J. Agardh. Chemical Engineering Journal 97, 249–255. The results showed that these seaweeds were characterized by an acceptable level of minerals and proteins. The genus of Sargassum can be distinguished from its leaves and stem parts. In a bid to harness the potential uses of the seaweed biomass, Its bioactivities vary depending on the algae species and the … Chemical and Mineral Composition of Six Potentially Edible Seaweed Species of Yucatán Oyesiku and Egunyomi (2014) also did proximate analysis and chemical composition analysis especially nitrogen, phosphorous and potassium on Sargassum samples found offshore in Ondo State, Nigeria. In Japanese waters, where it originates, it is a relatively small, innocuous seaweed (1-2 m in length). Sargassum naozhouense is a brown seaweed used in folk medicine and applied for thousands of years in Zhanjiang, Guangdong province, China. The effects were investigated of two different drying treatments (oven- andfreeze-drying) on the proximate composition, amino acid profile and somephysico-chemical properties of three subtropical brown seaweeds, Sargassum hemiphyllum, S. henslowianum and S. patens. Chemical Composition Proximate composition of general components in Sargassum swartzii. Quantify the changes in chemical composition and physiology of Sargassum plants as they form floating rafts.

Sargassum muticum is an invasive brown seaweed that has recently found its way to the shores of Ireland. Preliminary chemical characterization of this seaweed is important as a bioprospecting strategy for seaweed industry development. Its bioactivities vary depending on the algae species and the chemical structure. Jurnal Biofarmasi 2(2), 45-52. The pelagic seaweed found offshore and negatively impacting fishing activity in Ondo State Nigeria, has been identifiedto be a mixture of Sargassum natans and Sargassum fluitans which presumably floated from the Sagasso Sea of North Atlantic. 1988. This study is the first time to investigate its chemical composition and antiviral activity. Several factors that caused differences in chemical composition, and physical fucoidan include the condition of the place grow whether ocean currents wave, and the harvest season [18], the length of seaweed contact with the open air [19], the age of leaves where the older age of seaweed higher fucose content. Sargassum brown seaweed is known to have many health benefits and therapeutic effects. Abstract: Sargassum brown seaweed is known to have many health benefits and therapeutic effects. 2. 2. Hashim MA, Chu KH. In the context, the chemical composition (protein, carbohydrate, lipids, fiber, ash and nitrogen) of two seaweeds (Gracilaria cervicornis and Sargassum vulgare) from Northeast Brazil was investigated in order to evaluate their potential nutritive value. Following are the products of sargassum which is given below:- Fertilizers: Organic fertilizers are produced for the cultivation of horticulture crops like kharif, rabi, zaid, food crops, and plantation. ... plus its composition changes daily as it rots,” explains Prof Chris Chuck, the project’s lead chemical engineer at … Chemical composition diversity of fucoidans isolated from three tropical brown seaweeds (Phaeophyceae) species. The aim of the study was to determine the chemical and functional properties of five Kenyan seaweed species namely; (Hypnea musciformis, Eucheuma denticulatum, Laurencia intermedia, Sargassum oligocystum, Ulva fasciata) as a potential fat replacer in chicken sausage processing.
