Nutrient solutions, as opposed to fertilizers, are designed specifically for use in aquatic environments and their composition is much more precise. [2] In a unified system, algal biomass can be collected by utilizing carbon dioxide emanating from power plants and wastewater discharged by both industrial and domestic sources.
Porphyra is classified as red algae; it tends to be a brownish colour, but boils down to a dark green pulp when prepared. It is unusual amongst seaweeds because the fronds are only one cell thick. It is unusual amongst seaweeds because the fronds are only one cell thick.
The marine red alga Porphyra has been cultivated extensively in many Asian countries as an edible seaweed used to wrap the rice and fish that compose the Japanese food sushi and the Korean food gimbap. In Japan, the annual production of Porphyra species is valued at 100 billion yen (US$1 billion). [11]
Maerl (also rhodolith) is a collective name for non-geniculate coralline red algae with a certain growth habit. [1] Maerl grows at a rate of c. 1 mm per year. [ 2 ] It accumulates as unattached particles and forms extensive beds in suitable sublittoral sites. [ 3 ]
Gracilaria parvispora, also known by the common names long ogo, [1] red ogo, [2] or simply ogo, [3] is a large species of marine red alga in the genus Gracilaria, endemic to Hawaii. It is highly sought after as an edible seaweed and is popular in mariculture and the marine aquarium trade .
Jania is an articulated coralline algae characterized by having erect thalli with dichotomously-arranged branches composed of alternating segments of red or pink, calcified, cylindrical sections (intergeniculum) and white uncalcified sections (geniculum); that is attached to the substrate by small, stolon-like holdfasts.
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 . The polysaccharides of this species are sulfated and their structure gives rise to some unique properties that could lead ...
Red algae, like Gracilaria, Gelidium, Euchema, Porphyra, Acanthophora, and Palmaria are primarily known for their industrial use for phycocolloids (agar, algin, furcellaran and carrageenan) as thickening agent, textiles, food, anticoagulants, water-binding agents, etc. [87] Dulse (Palmaria palmata) is one of the most consumed red algae and is a ...
