Nutritional composition of edible Hawaiian seaweeds

Proximate Composition of Bio Potential Seaweeds from Mandapam South East Coast of India

“…[26] Although, according to the previously reported values in the literature, most of the macro algae are covered lipid lesser value than 4% DW however, some macroalgae had higher amount of crude lipid such as Dictyota acutiloba (16.1% DW) and D. sandvicenis (20.2 % DW). [30] The measured lipid contents in the present study are in consistency with that reported in Caulerpa racemosa, and Padina gymnospora, 19.1 %, and 11.4%, respectively However, they are upper than those determined previously for Ulva lactuca, (7.87-1.64 % DW) and (0.3-1.64% dry weight). [22,23,31] Presence of highest fat content of 21.25 mg/g in the seaweed E. compressa and a minimum of 11.67 mg/g in C. aerea of the current study closely depicting with the previous work carried out in this line.…”

Biosorption of phenanthrene by pure algae and field-collected planktons and their fractions

“…Lipids show the bands at 2800 and 2950 cm À1 for aliphatic chains (Blokker et al, 1998;Rodríguez and Cerezo, 1996;Mecozzi et al, 2011). In the previous investigation, it was found that the major components of algae are lipids, proteins, carbohydrates together with smaller amount of resistant polymers (such as algaenan) (Renaud et al, 1994;McDermid and Stuercke, 2003). Hence, the investigated samples are confirmed to be the combination of several biomolecules (proteins, carbohydrates, lipids, and algaenan).…”

Plants and algae species: Promising renewable energy production source

“…While few others naturally build up high amount of TAG (up to 60% of dry weight), show highly efficient photosynthesis and production of lipid higher than that produced by terrestrial crops (Zhu et al, 2008). Generally carbohydrates accumulation dominates in macro algae and cyanobacteria while lipid is less than 5% of total dry (Mcdermid and Stuercke, 2003); although 50% lipid is reported in few species. Among biologically generated hydrogen and alcohols, lipids and carbohydrates are probable biofuels and biofuel precursors.…”

“…The primary biochemical feedstocks, the polysaccharides like mannitol, lamarin and flucoidin are used to form liquid fuels (McHugh, 2003). The content of lipid in most of the macroalgal species is not more than 5% of total dry weight which is very low for biodiesel production, even though some species are believed to produce around 20% (McDermid and Stuercke, 2003). The methods that can process whole algae are pyrolysis, gasification, supercritical processing and anaerobic digestion (Kumar, 2012).…”
