What is the use of Gelidium?
capense (as G. cartilagineum) are extracted to produce high quality agar, a sulphated polysaccharide used widely in the food, pharmaceutical and cosmetic industries. Traditionally Gelidium is consumed as a vegetable and for making agar jelly.
Where is Gelidium found?
Gelidium sesquipedale is mainly found on the Atlantic coast of Morocco, Spain, Portugal and France, while Gracilaria verrucosa grows on the coastline of Chile, Argentina, Indonesia, South Korea and Japan (Benech 2008).
What is the importance of Gelidium?
Gracilaria has become the preferred seaweed for making food grade agar because it has been successfully cultivated in Chile and Indonesia. Gelidium continues to be the preferred seaweed for making bacteriological and pharmaceutical grade agars and agarose.
What is Gelidium and Gracilaria?
Agar is obtained mostly from polysaccharides from red seaweed, primarily from the orders Gracilariales and Gelidiales. Gelidium species usually occur on rocky shores, while Gracilaria species grow mostly in sandy habitats. Higher-quality agar is extracted from Gelidium species, based on the gel strength (McHugh 1987).
Is Gelidium unicellular or multicellular?
Anabaena is Cyanobacteria, Laminaria, Sargassum, Gelidium, Gracilaria are multicellular algae. Volvox is unicellular colonial algae.
Where does Gelidium grow?
