Kappaphycus alvarezii, the elkhorn sea moss, is a species of red algae. The elkhorn sea moss varies in size, weight, and age. It is a dark greenish-brown hue and can sometimes be deep purple. The moss is cylindrical in shape throughout the seaweed. Its diameter averages 1.526 mm when dried. [1]
Red algae of the Rhodophyceae are common in a freshwater aquarium setting. Despite the name, red algae species usually present as a grayish color. [2] Zhan et al. (2020), using DNA barcoding, found 13 different operational taxonomic units of red algae growing within freshwater aquarium stores in Taiwan. [1] [a]
A Red tide is a discoloration of the sea water by pigmented cells like Gonyaulax spp., some of which may produce toxins. Gonyaulax spinifera has been connected to the production of yessotoxins (YTXs), a group of structurally related polyether toxins, which can accumulate in shellfish.
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 ...
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 .
Galdieria is a genus of red algae belonging to the order Galdieriales; [1] family Galdieriaceae. [2] It was created by an Italian botanist Aldo Merola in 1981 for the identification from the species of Cyanidium. [3] [4] Species: [2] Galdieria daedala O.Yu.Sentsova, 1991; Galdieria maxima O.Yu.Sentsova, 1991; Galdieria partita O.Yu.Sentsova, 1991
Many of the algae in this genus are used to make agar. [1] Agarocolloids are known to be extracted in algae belonging to the orders Gracilariales and Gelidiales with certain applications in the food and cosmetics. Gelling properties often differ among species, seasons, seaweed age, and substitutions between sulphate esters, among other compounds.
Porphyra is a genus of coldwater seaweeds that grow in cold, shallow seawater.More specifically, it belongs to red algae phylum of laver species (from which comes laverbread), comprising approximately 70 species. [2]
