A range of microalgae species are produced in hatcheries and are used in a variety of ways for commercial purposes, including for human nutrition, [19] as biofuel, [20] in the aquaculture of other organisms, [21] in the manufacture of pharmaceuticals and cosmetics, [22] and as biofertiliser. [23]
Porphyridium cruentum is a species of red algae in the family Porphyridiophyceae.. The microalga Porphyridium sp. is a potential source for several products like fatty acids, lipids, cell-wall polysaccharides and pigments .
Organotrophs use organic compounds as electron/hydrogen donors. Lithotrophs use inorganic compounds as electron/hydrogen donors.. The electrons or hydrogen atoms from reducing equivalents (electron donors) are needed by both phototrophs and chemotrophs in reduction-oxidation reactions that transfer energy in the anabolic processes of ATP synthesis (in heterotrophs) or biosynthesis (in autotrophs).
Nutrient density identifies the amount of beneficial nutrients in a food product in proportion to e.g. energy content, weight or amount of perceived detrimental nutrients.. Terms such as nutrient rich and micronutrient dense refer to similar properti
The Dietary Reference Intake (DRI) is a system of nutrition recommendations from the National Academy of Medicine (NAM) [a] of the National Academies (United States). [1] It was introduced in 1997 in order to broaden the existing guidelines known as Recommended Dietary Allowances (RDAs, see below).
Phosphorus occurs in amounts of about 2/3 of calcium, and makes up about 1% of a person's body weight. [10] The other major minerals (potassium, sodium, chlorine, sulfur and magnesium) make up only about 0.85% of the weight of the body. Together these eleven chemical elements (H, C, N, O, Ca, P, K, Na, Cl, S, Mg) make up 99.85% of the body.
All macronutrients except water are required by the body for energy, however, this is not their sole physiological function. The energy provided by macronutrients in food is measured in kilocalories, usually called Calories, where 1 Calorie is the amount of energy required to raise 1 kilogram of water by 1 degree Celsius.
Dunaliella salina is a type of halophile unicellular green algae especially found in hypersaline environments, such as salt lakes and salt evaporation ponds. [2] Known for its antioxidant activity because of its ability to create a large amount of carotenoids , it is responsible for most of the primary production in hypersaline environments ...
