Coral reefs have undergone profound ecological changes over recent decades. Areas formerly covered by scleractinian coral species are now often overgrown by macroalgae. In Martinique (West Indies), this phenomenon has lead to the colonisation of numerous coral reefs by algae, amongst which Sargassum is one of the most prominent. This study focuses on potential defence molecules produced by Sarg...

Sargassum has been well acknowledged for the potential natural product of its phlorotannins. Solid-liquid extraction (SLE) is the most common method used to extract them. However, this method has some drawbacks such as low yield and toxic. An alternative ecofriendly method has been proposed, i.e. enzyme-assisted extraction (EAE), proven to be more efficient. The aim is to compare the efficiency...

The release of chromium into water bodies is one of the major concerns of tannery industries. The present work deals with the determination of Chromium removal capacity of powdered biomass of Sargassum wightii (Greville) in synthetically prepared as well as real tannery effluent. The maximum adsorption was obtained after 12 hours of exposure at pH-4, in 8g/L biomass concentration of the seaweed...

Algae have long been used to augment plant productivity through their beneficial effects. Alginate oligosaccharide is believed to be one of the important components to enhance growth and crop yield. In this study, we isolated and characterized a Bacillus litoralis strain, named Bacillus M3, from decayed kelps. We further demonstrated that the M3 strain could secrete alginate lyase to degrade al...

Seventy five patients with oral lesions attending the different departments of Rajah Muthiah Medical College and Hospital, Annamalai University were screened for Candida. Forty six (61.3%) Candida strains were isolated from the oral lesions. Of the 46 Candida strains, Candida albicans accounted for 35 (76.08%), Candida glabrata for 5 (10.86%), Candida tropicalis and Candida krusei for 2 (4.34%)...

This study investigated the effect of Sargassum angustifolium and Gracilaria pulvinata extracts on the growth performance, body composition, antioxidant status and gut microbiota of rainbow trout (Oncorhynchus mykiss) fry. For this purpose, 540 fry of rainbow trout (initial weight 0.23±0.04 g) were distributed in 12 fiberglass tanks. Fish were fed with experimental diets containing 500 mg kg-1 ...

During our on-going screening program designed to isolate natural compounds from marine environments, we isolated isoketochabrolic acid (IKCA) from Sargassum micracanthum, an important brown algae distributed in Jeju Island, Korea. Furthermore, we evaluated the inhibitory effects of IKCA on nitric oxide (NO) production in lipopolysaccharide (LPS)-triggered macrophages. IKCA strongly inhibited N...

More than 3000 MT of Sargassum illicifolium ,annually washed-up from the Oman Sea (Sistan and Baluchestan province). , According to the estimates of the Iranian Fisheries Sciences Researchinstitiute.The brown seaweed biomass has been considered as one of the best free sources for production of sodium alginate. A key objective of this study was to determine the biochemical composition of Sargass...

Massive quantities of the pelagic brown macroalgae Sargassum spp. (sargassum) have been invading Caribbean and West African shores since 2011, causing devastating effects on coastal ecosystem local economy. Little is known about sargassum beaching dynamics capacity system to naturally remove beached sargassum. Here, we characterize temporal variation in arriving a reef lagoon using 5.2-year dat...

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...
