Haematococcus
''Haematococcus'' is a genus of algae in the family Haematococcaceae. Members of this group are a common cause of the pink color found in birdbaths. One of the most notable species of ''Haematococcus'' is ''H. pluvialis'', which is used in cosmetic products due to its production of astaxanthin, a powerful antioxidant carotenoid, under stress conditions.

Chlamydomonadales
Chlamydomonadales, also known as Volvocales, are an order of flagellated or pseudociliated green algae, specifically of the Chlorophyceae.See the NCBIbr>webpage on Chlamydomonadales Data extracted from the Chlamydomonadales can form planar or spherical colonies. These vary from ''Gonium'' (four to 32 cells) up to ''Volvox'' (500 cells or more). Each cell has two flagella, and is similar in appearance to ''Chlamydomonas'', with the flagella throughout the colony moving in coordination. Both asexual and sexual reproduction occur. In the former, cells divide until they form new colonies, which are then released. In the smaller forms, typically all cells are involved, but larger forms have anterior vegetative and posterior reproductive cells. Sexual reproduction varies from isogamy (both genders produce flagellated gametes of equal size) to oogamy (one gender produces a much larger, nonmotile gamete). The classification of the Chlamydomonadales varies. Very often they are taken ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gungnir (alga)
In Norse mythology, Gungnir (, "the rocking") is the spear of the god Odin. Attestations ''Poetic Edda'' In the Poetic Edda poem ''Völuspá'', the Æsir-Vanir War is described as officially starting when Odin throws a spear over the heads of an assembly of Vanir gods. Whether or not this was specifically Gungnir is, however, unstated. In ''Sigrdrífumál'', the valkyrie Sigrdrífa advises Sigurd on the magical application of runes. She gives Sigurd advice and shares with him lore, including that runes were carved on the tip of Gungnir. ''Prose Edda'' According to chapter 51 of the ''Prose Edda'' book, ''Gylfaginning'', Odin will ride in front of the Einherjar while advancing on to the battle field at Ragnarök wearing a gold helmet, an impressive cloak of mail and carrying Gungnir. He will then attack the wolf Fenrir with it. In ''Skáldskaparmál'', more information regarding the spear is presented. The spear was fashioned by the dwarves known as the Sons of Ivaldi under ...

Rusalka (alga)
In Slavic folklore, the rusalka (plural: rusalky/rusalki; ; pl, rusałka}) is a typically feminine entity, often malicious toward mankind and frequently associated with water, with counterparts in other parts of Europe, such as the French Melusine and the Germanic Nixie. Folklorists have proposed a variety of origins for the entity, including that they may originally stem from Slavic paganism, where they may have been seen as benevolent spirits. Rusalki appear in a variety of media in modern popular culture, particularly in Slavic language-speaking countries, where they frequently resemble the concept of the mermaid. In northern Russia, the rusalka was also known by various names such as the vodyanitsa (or vodyaniha/vodyantikha; russian: водяни́ца, водяни́ха, водянти́ха ; lit. "she from the water" or "the water maiden"), kupalka (russian: купа́лка; "bather"), shutovka (russian: шуто́вка; "joker", "jester" or "prankster") and loskotu ...

Green Algae
The green algae (singular: green alga) are a group consisting of the Prasinodermophyta and its unnamed sister which contains the Chlorophyta and Charophyta/Streptophyta. The land plants (Embryophytes) have emerged deep in the Charophyte alga as sister of the Zygnematophyceae. Since the realization that the Embryophytes emerged within the green algae, some authors are starting to properly include them. The completed clade that includes both green algae and embryophytes is monophyletic and is referred to as the clade Viridiplantae and as the kingdom Plantae. The green algae include unicellular and colonial flagellates, most with two flagella per cell, as well as various colonial, coccoid and filamentous forms, and macroscopic, multicellular seaweeds. There are about 22,000 species of green algae. Many species live most of their lives as single cells, while other species form coenobia (colonies), long filaments, or highly differentiated macroscopic seaweeds. A few other organi ...

Algaculture
Algaculture is a form of aquaculture involving the farming of species of algae. The majority of algae that are intentionally cultivated fall into the category of microalgae (also referred to as phytoplankton, microphytes, or planktonic algae). Macroalgae, commonly known as seaweed, also have many commercial and industrial uses, but due to their size and the specific requirements of the environment in which they need to grow, they do not lend themselves as readily to cultivation (this may change, however, with the advent of newer seaweed cultivators, which are basically algae scrubbers using upflowing air bubbles in small containers). Commercial and industrial algae cultivation has numerous uses, including production of nutraceuticals such as omega-3 fatty acids (as algal oil) or natural food colorants and dyes, food, fertilizers, bioplastics, chemical feedstock (raw material), protein-rich animal/aquaculture feed, pharmaceuticals, and algal fuel, and can also be used as a means ...

Astaxanthin
Astaxanthin is a keto- carotenoid within a group of chemical compounds known as terpenes. Astaxanthin is a metabolite of zeaxanthin and canthaxanthin, containing both hydroxyl and ketone functional groups. It is a lipid-soluble pigment with red coloring properties, which result from the extended chain of conjugated (alternating double and single) double bonds at the center of the compound. Astaxanthin is produced naturally in the freshwater microalgae ''Haematococcus pluvialis'' and the yeast fungus ''Xanthophyllomyces dendrorhous'' (also known as ''Phaffia rhodozyma''). When the algae are stressed by lack of nutrients, increased salinity, or excessive sunshine, they create astaxanthin. Animals who feed on the algae, such as salmon, red trout, red sea bream, flamingos, and crustaceans (shrimp, krill, crab, lobster, and crayfish), subsequently reflect the red-orange astaxanthin pigmentation. Astaxanthin is used as a dietary supplement for human, animal, and aquaculture co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chlorophyceae Families
The Chlorophyceae are one of the classes of green algae, distinguished mainly on the basis of ultrastructural morphology. They are usually green due to the dominance of pigments chlorophyll a and chlorophyll b. The chloroplast may be discoid, plate-like, reticulate, cup-shaped, spiral or ribbon shaped in different species. Most of the members have one or more storage bodies called pyrenoids located in the chloroplast. Pyrenoids contain protein besides starch. Some green algae may store food in the form of oil droplets. They usually have a cell wall made up of an inner layer of cellulose and outer layer of pectose. General characteristics * the body may be unicellular, colonial, filamentous or multicellular. * They are usually green due to the presence of chlorophyll a, chlorophyll b and beta-carotene. * The chloroplast may be discoid, cup-shaped (e.g. ''Chlamydomonas''), spiral or ribbon shaped * Most chlorophytes have one or more storage bodies called pyrenoids (central prot ...
