Eucheuma Denticulatum
''Eucheuma denticulatum'' is a species of red algae and one of the primary sources of iota carrageenan. It exists naturally in the Philippines, tropical Asia, and the western Pacific, but for the commercial extraction of carrageenan it is usually cultivated. The species is commonly known as ''E. spinosum'' when cultivated and can be found in different colours: brown, green and red. Cultivation of ''Eucheuma'' started in the Philippines in the early 1970s and has since been introduced to many other locations with varying results. There are different methods of cultivating ''E. denticulatum''. One of the more common ones is the off-bottom "tie-tie"-method, with the setup being two stakes driven into the sediment with a rope between them. Pieces of the seaweed are then tied to the rope at regular intervals and allowed to grow for 6 weeks, after which it is harvested and dried. The species was originally described in 1768 as ''Fucus denticulatus'' by Nicolaas Laurens Burman Nicola ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nicolaas Laurens Burman
Nicolaas Laurens Burman (27 December 1734 – 11 September 1793) was a Dutch botanist. He was the son of Johannes Burman (1707–1780). He succeeded his father to the chair of botany at the Athenaeum Illustre of Amsterdam., and at the Hortus Botanicus (Amsterdam), Hortus Botanicus. He continued the correspondence with Carl Linnaeus, joining him at the University of Uppsala in 1760. He is the author of numerous works including ''Specimen botanicum de geraniis'' (1759) and ''Flora Indica'' (1768) which was later completed by Johann Gerhard Koenig (1728–1785).

Red Algae
Red algae, or Rhodophyta (, ; ), make up one of the oldest groups of eukaryotic algae. The Rhodophyta comprises one of the largest Phylum, phyla of algae, containing over 7,000 recognized species within over 900 Genus, genera amidst ongoing taxonomic revisions. The majority of species (6,793) are Florideophyceae, and mostly consist of multicellular, ocean, marine algae, including many notable seaweeds. Red algae are abundant in marine habitats. Approximately 5% of red algae species occur in freshwater environments, with greater concentrations in warmer areas. Except for two coastal cave dwelling species in the asexual class Cyanidiophyceae, no terrestrial species exist, which may be due to an evolutionary bottleneck in which the last common ancestor lost about 25% of its core genes and much of its evolutionary plasticity. Red algae form a distinct group characterized by eukaryotic cells without flagella and centrioles, chloroplasts without external endoplasmic reticulum or unstack ...

Carrageenan
Carrageenans or carrageenins ( ; ) are a family of natural linear sulfation, sulfated polysaccharides. They are extracted from red algae, red edible seaweeds. Carrageenans are widely used in the food industry, for their gelling, thickening, and stabilizing properties. Their main application is in dairy and meat products, due to their strong binding to food proteins. Carrageenans have emerged as a promising candidate in tissue engineering and regenerative medicine applications as they resemble animal glycosaminoglycans (GAGs). They are used for tissue engineering, wound coverage, and drug delivery. Carrageenans contain 15–40% ester-sulfate content, which makes them anionic polysaccharides. They can be mainly categorized into three classes based on their sulfate content. Kappa-carrageenan has one sulfate group per disaccharide, iota-carrageenan has two, and lambda-carrageenan has three. A common seaweed used for manufacturing the hydrophilic colloids to produce carrageenan is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Philippines, officially the Republic of the Philippines, is an Archipelagic state, archipelagic country in Southeast Asia. Located in the western Pacific Ocean, it consists of List of islands of the Philippines, 7,641 islands, with a total area of roughly 300,000 square kilometers, which are broadly categorized in Island groups of the Philippines, three main geographical divisions from north to south: Luzon, Visayas, and Mindanao. With a population of over 110 million, it is the world's List of countries and dependencies by population, twelfth-most-populous country. The Philippines is bounded by the South China Sea to the west, the Philippine Sea to the east, and the Celebes Sea to the south. It shares maritime borders with Taiwan to the north, Japan to the northeast, Palau to the east and southeast, Indonesia to the south, Malaysia to the southwest, Vietnam to the west, and China to the northwest.

Fucus
''Fucus'' is a genus of brown algae found in the intertidal zones of rocky seashores almost throughout the world. Description and life cycle The thallus is perennial with an irregular or disc-shaped holdfast or with haptera. The erect portion of the thallus is dichotomous or subpinnately branched, flattened and with a distinct midrib. Gas-filled pneumatocysts (air- vesicles) are present in pairs in some species, one on either side of the midrib. The erect portion of the thallus bears cryptostomata and caecostomata (sterile surface cavities). The base of the thallus is stipe-like due to abrasion of the tissue lateral to the midrib and it is attached to the rock by a holdfast. The gametangia develop in conceptacles embedded in receptacles in the apices of the final branches. They may be monoecious or dioecious. These algae have a relatively simple life cycle and produce only one type of thallus which grows to a maximum size of 2 m. Fertile cavities, the conceptacle ...
