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...

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.

BACKGROUND The preference for a fairer skin-tone has become a common trend among both men and women around the world. In this study, seaweeds Sargassum polycystum and Padina tenuis were investigated for their in vitro and in vivo potentials in working as skin whitening agents. Seaweed has been used as a revolutionary skin repairing agent in both traditional and modern preparations. The high ant...

The antibacterial activity of crude extracts of Sargassum longifolium and Gracilaria corticata collected from the Gulf of Mannar Coast, Tamilnadu, India against common shrimp pathogens were tested by disc diffusion method. Three different solvents namely aqueous, ethanol and methanol were used for extraction. The qualitative phytochemical analysis revealed the presence of carbohydrates, protein...

BACKGROUND AND OBJECTIVES Sixty ethanol extracts of marine flora of Baja California Sur (Mexico) were screened to evaluate the reversing effect of the bacterial resistance to antibiotics in combination with a sublethal concentration of ampicillin or erythromycin. MATERIALS AND METHODS The activity was assayed by using a modification of the classical agar-diffusion method against 3 resistant, ...
