The lack of a genetic transformation system that allows integration of a foreign gene into the genome is a serious hindrance to progress in biological research on seaweeds. In contrast, physiological research in seaweeds has a long history of focus on the establishment of cell polarity and multicellularity (Brownlee and Bouget, 1998; Hable and Hart, 2010). Today, nuclear genomes have been recen...

Spent biomass of different seaweeds such as Sargassum wightii, Turbinaria conoides, Padina tetrastomata and Ulva lactuca were evaluated for the nutritional benefits in aqua feeds. Basic nutritional value, of seaweeds contains a number of pigments, defensive and storage compounds, and secondary metabolites that could have beneficial effects in farmed fish. Only a small fraction of algal species ...

Marine macroalgae, or seaweeds, are a formidable source of natural compounds with diverse biological activities. In the last five decades it has been estimated that more than 3000 natural compounds were discovered from these organisms. The great majority of the published works have focused on terpenoids. In comparison, glycolipids are a neglected class of macroalgal secondary metabolites theref...

Because seaweeds uncontrolled by herbivores can overgrow and kill corals, competition can exclude corals from temperate latitudes where herbivores generally fail to control seaweed biomass. In this study, we show that the coral Oculina arbuscula persists on reefs in temperate North Carolina where seaweeds are common by harboring the omnivorous crab Mithrax forceps, which removes seaweeds and in...

Seaweeds are highly perishable foods due to their richness in nutrients. High pressure processing (HPP) has been applied for extending the shelf life of fresh seaweeds but there is no information on effect HPP bacterial diversity seaweeds. The culturable bacteria six species edible (green Codium fragile and Ulva lactuca, brown Himanthalia elongata, Laminaria ochroleuca Undaria pinnatifida, red ...

The two red seaweeds, Gracilaria manilaensis and Kappaphycus alvarezii are cultivated in Malaysia for producing agar and carrageenan, respectively. The residues of these seaweeds after removing agar and carrageenan by dilute acid treatment were subjected to enzymatic hydrolysis using cellulase (Cellic CTec 2). In the optimization of enzymatic hydrolysis, highest glucose concentration was achiev...

sea algae are widely consumed in the world. there are several seaweeds including brown algae which are authorized for human consumption. these plants contain important phytochemical constituents and have various potential biological activities. the present study investigated the presence of phytochemical constituents and total phenolic quantity of the seaweeds sargassum angustifolium , sargassu...

Marine algal community signifies a huge source of compound endowed with ingenious structure and potential biological activities. Cytotoxicity of plant or fungal material is considered as the presence of antitumor compounds. In this study, ethanol extracts of seaweeds Dictyota dichotoma var. velutricata, D. hauckiana, D. indica, Iyengaria stellata, Jolyna laminarioides, Melanothamnus afaqhusaini...
