The amount of sargassum seaweed washed ashore on the beaches Africa, Brazil, Central America and Caribbean has increased to point where it become a social, environmental financial issue. This research evaluates potential for Sargassum spp. Mexican coast be used in production biomethane by estimating: a) stoichiometric methane (SMP), b) biochemical (BMP) c) biodegradability index (BI). use sigmo...

Rumput laut merupakan sumber daya hayati yang melimpah di perairan Indonesia tumbuh pada substrat bebatuan. memiliki potensi sebagai bahan pangan alternatif dengan nilai kandungan nutrisi besar. Sargassum rumput dalam kelas Phaeophyta atau coklat. coklat diketahui mempunyai (kadar karbohidrat, protein, lemak), mineral esensial dan juga mengandung senyawa bioaktif, berdasarkan hasil dari metabol...

BACKGROUND AND OBJECTIVES Antitumor drug resistance and side effects of antitumor compounds are the most common problems in medicine. Therefore, finding new antitumor agents with low side effects could be interesting. This study was designed to assay antitumor activity of the extract from brown alga Sargassum oligocystum, gathered from Persian Gulf seashore, against K562 and Daudi human cancer ...

A detailed, methodical approach was used to synthesise silver and gold nanoparticles using two differently prepared aqueous extracts of the brown algae Sargassum incisifolium. The efficiency of the extracts in producing nanoparticles were compared to commercially available brown algal fucoidans, a major constituent of brown algal aqueous extracts. The nanoparticles were characterised using TEM,...

cales) are known to contain structurally unique secondary metabolites, such as plastoquinones, chromanols, a cyclopentenone, and polysaccharides. These compounds show various biological activities due to their unique structure. We previously reported that the methanolic extract of the brown alga, Sargassum micracanthum (KUETZING) ENDLICHER, “Togemoku” in Japanese, showed strong antioxidant acti...

Antimicrobial Activities and Bioactive Metabolites from Marine Algae Valoniopsis pachynema and Sargassum swartzii Devaraj Isaac Dhinakaran1*, Ravichandran Rajalakshmi1, Thangavel Sivakumar2, Solomon Jeeva3 1Department of Biotechnology, Ayya Nadar Janaki Ammal college, Sivakasi-626124, Tamilnadu, India. 2Department of Microbiology, Ayya Nadar Janaki Ammal college, Sivakasi-626124, Tamilnadu, Ind...

The present study was aimed to optimize the protocol for the synthesis of silver nanoparticles using aqueous extracts of Sargassum swartzii (Turner) C.Agardh and evaluate cytotoxic potetnials using brine shrimp bio-assay activity and Trypan blue dye exclusion method. The reduction of pure Ag+ ions was monitored by measuring the UV-Vis spectrum of the solution at 200-900 nm using Shimadzu spectr...

The aim of the present study is to evaluate the protective effect of polysaccharide from the Brown Seaweed Sargassum graminifolium (SGP) on ethylene glycol-induced kidney damage and the mechanism of SGP-mediated protection. Mitochondrial lipid peroxidation, mitochondrial swelling, the activity of succinate dehydrogenase (SDH), ATPases and mitochondrial antioxidant enzymes was observed in hypero...

The alxM gene encoding a D-mannuronan-specific alginate lyase has been cloned from a marine bacterium isolated as an epiphyte on the brown alga, Sargassum fluitans. Expression of this gene in Escherichia coli provides a source of this enzyme for probing alginate structure and modifying the mannuronan-rich alginate polymers produced by bacterial pathogens.
