The red seaweeds belonging to the genus Laurencia are well known as halogenated secondary metabolites producers, mainly terpenoids and acetogennins. Several of these chemicals exhibit important ecological roles and biotechnological applications. However, knowledge regarding the genes involved in the biosynthesis of these compounds is still very limited. We detected 20 different genes involved i...

Species traits have been used extensively in invasion science, providing common metrics across taxa and ecosystems that enable comparisons based on the functional responses effects of biota. However, most work science has focused terrestrial plants, despite vulnerability aquatic to invasive species, such as seaweeds. Research focuses individual species seaweeds intensified recent years, yet few...

Seaweeds have been used since ancient times as food, food additives, fertilizer, and a source of medicine. Like terrestrial plants, seaweeds contain many inorganic organic substances which can beneficial to human health. great potential “bioactive compounds for functional use, “algae mineral supplements”, “pharmaceuticals cosmetics” in addition their good sources minerals, trace elements, prote...

Seaweeds have a variety of biological activities, and their aromatic characteristics could play an important role in consumer acceptance. Here, changes aroma compounds were monitored during microbial fermentation, those most likely to affect sensory perception identified. Ulva sp. Laminaria fermented generally recognized as safe microorganisms, the profile volatile seaweeds was investigated usi...

The nutritional value of six tropical seaweeds (Sargassum wightii, Ulva lactuca, Kappaphycus alvarezii, Hypnea musciformis, Acanthophora spicifera and Gracilaria corticata) as complementary source of dietary proteins for human and animal nutrition based on amino acid profile was evaluated. All these species showed similar non-essential amino acid patterns in which aspartic and glutamic acids co...

Water is one of the most important natural phenomena to be rendered in computer graphics. Although ocean waves animation has been well studied in Computer graphics, only few studies have been done for underwater animation. In this paper, we present a new real-time method for animation of suspended particles and seaweeds in underwater scenes. One of the main advantages of this method, compared t...

Plant and animal biomechanists have much in common. Although their frame of reference differs, they think about the natural world in similar ways. While researchers studying animals might explore airflow around flapping wings, the actuation of muscles in arms and legs, or the material properties of spider silk, researchers studying plants might explore the flow of water around fluttering seawee...

Aqueous extracts of four seaweeds collected from Gulf of Mannar coastal waters were tested for α-amylase and α-glucosidase inhibition properties. The aqueous extracts of seaweeds in the order of Gracilaria edulis, Sargassum polycystum, Ulva lactuca and Gracilaria corticata showed significant inhibitory activity against α-amylase and α-glucosidase enzymes. G. edulis was found to be a potent inhi...

The marine carotenoid fucoxanthin can be found in marine brown seaweeds, the macroalgae, and diatoms, the microalgae, and has remarkable biological properties. Numerous studies have shown that fucoxanthin has considerable potential and promising applications in human health. In this article, we review the current available scientific literature regarding the metabolism, safety, and bioactivitie...
