Blidingia minima is a species of seaweed in the Kornmanniaceae family. It was described by Johann Kylin in 1947. [2]
The species is 1–10 centimetres (0.39–3.94 in) long by 1–2 millimetres (0.039–0.079 in) wide and is light green in colour. [3] It fronds are tubular with it cell arrangement being irregular and 10 micrometres (0.00039 in) in diameter. Stellate chloroplasts also exist. The tubes rise in groups from the center. [4] It thalli grow as clusters which carry cylindrical and hollow tubes which arise from discoidal cushion. [5] The tubes are 1–20 millimetres (0.039–0.787 in) long and 2 millimetres (0.079 in) wide. Thallus cells are 7 micrometres (0.00028 in) wide and are angular. [6]
The species is found throughout eastern part of Asia in such countries as China, Japan, Korea and eastern part of Russia. [5] It is also found in Azores, Canada, Norway, South Africa, United States, and various gulfs, seas and oceans, such as Gulf of Maine and Gulf of Mexico and in Atlantic and Pacific Oceans and Wadden Sea. [2] Besides this places it have a type locality which is Helgoland, Germany [7] and is also common in Ireland and Great Britain. [8] It was recorded in Queensland, Australia as well. [9]
In England, the species was recorded from East Sussex. [10]
It is found growing on cobble, boulders, bedrocks, barnacles, driftwood and even on different algae species throughout the semi-protected and protected areas. [5]
Blidingia minima is considered to be a food for periwinkles. [11]
Chlorophyta is a taxon of green algae informally called chlorophytes. The name is used in two very different senses, so care is needed to determine the use by a particular author. In older classification systems, it is a highly paraphyletic group of all the green algae within the green plants (Viridiplantae) and thus includes about 7,000 species of mostly aquatic photosynthetic eukaryotic organisms. In newer classifications, it is the sister clade of the streptophytes/charophytes. The clade Streptophyta consists of the Charophyta in which the Embryophyta emerged. In this latter sense the Chlorophyta includes only about 4,300 species. About 90% of all known species live in freshwater. Like the land plants, green algae contain chlorophyll a and chlorophyll b and store food as starch in their plastids.
Phycology is the scientific study of algae. Also known as algology, phycology is a branch of life science.
The sea lettuces comprise the genus Ulva, a group of edible green algae that is widely distributed along the coasts of the world's oceans. The type species within the genus Ulva is Ulva lactuca, lactuca being Latin for "lettuce". The genus also includes the species previously classified under the genus Enteromorpha, the former members of which are known under the common name green nori.
Sphaeropleales is an order of green algae that used to be called Chlorococcales. The order includes some of the most common freshwater planktonic algae such as Scenedesmus and Pediastrum. The Spaeropleales includes vegetatively non-motile unicellular or colonial taxa that have biflagellate zoospores with flagella that are directly opposed in direction : Sphaeroplea, Atractomorpha, Neochloris, Hydrodictyon, and Pediastrum. All of these taxa have basal body core connections.
Halimeda is a genus of green macroalgae. The algal body (thallus) is composed of calcified green segments. Calcium carbonate is deposited in its tissues, making it inedible to most herbivores. However one species, Halimeda tuna, was described as pleasant to eat with oil, vinegar, and salt.
Codium is a genus of edible green macroalgae under the order Bryopsidales. The genus name is derived from a Greek word that pertains to the soft texture of its thallus. One of the foremost experts on Codium taxonomy was Paul Claude Silva at the University of California, Berkeley. P.C. Silva was able to describe 36 species for the genus and in honor of his work on Codium, the species C. silvae was named after the late professor.
Monostroma is a genus of marine green algae (seaweed) in the family Monostromataceae. As the name suggests, algae of this genus are monostromatic. Monostroma kuroshiense, an algae of this genus, is commercially cultivated in East Asia and South America for the edible product "hitoegusa-nori" or "hirohano-hitoegusa nori", popular sushi wraps. Monostroma oligosaccharides with degree of polymerization 6 prepared by agarase digestion from Monostroma nitidum polysaccharides have been shown to be an effective prophylactic agent during in vitro and in vivo tests against Japanese encephalitis viral infection. The sulfated oligosaccharides from Monostroma seem to be promising candidates for further development as antiviral agents. The genus Monostroma is the most widely cultivated genus among green seaweeds.
Trebouxia is a unicellular green alga. It is a photosynthetic organism that can exist in almost all habitats found in polar, tropical, and temperate regions. It can either exist in a symbiotic relationship with fungi in the form of lichen or it can survive independently as a free-living organism alone or in colonies. Trebouxia is the most common photobiont in extant lichens. It is a primary producer of marine, freshwater and terrestrial ecosystems. It uses carotenoids and chlorophyll a and b to harvest energy from the sun and provide nutrients to various animals and insects.
Trichosarcina is a genus of green algae in the order Ulotrichales. Filoprotococcus was once regarded as a synonym. However, Filoprotococcus is now considered valid in its own right. Trichosarcina is considered to be of uncertain validity.
Valonia is a genus of green algae in the Valoniaceae family. The genus Ventricaria is now regarded as a synonym of Valonia.
Pediastrum duplex is a species of fresh water green algae in the genus Pediastrum.
Ulva linza is a green alga in the family Ulvaceae that can be found in British Isles.
Laurencia is a genus of red algae that grow in temperate and tropical shore areas, in littoral to sublittoral habitats, at depths up to 65 m (213 ft).
Ulva conglobata is a species of seaweed in the family Ulvaceae that can be found on Jeju Island of Korea, Qingdao province of China and Yokohama, Japan.
Blidingia marginata is a species of seaweed in the Kornmanniaceae family.
Hypnea is a genus of red algae, and a well known carrageenophyte.
Monostroma kuroshiense, a green alga in the division Chlorophyta, is a green seaweed endemic to Kuroshio Coast of Japan. This high-value seaweed is called Hitoegusa or Hirohano hitoegusa (ヒロハノヒトエグサ) in Japanese. Previously this algae was known in binomen Monostroma latissimum, but the latest scientific research based on multilocal phylogeny discovered that this is a new species. The algae is named after Kuroshio Current, naming is done by phycologist Felix Bast This algae is commercially cultivated in East Asia and South America for the edible product "hitoegusa-nori" or "hirohano-hitoegusa nori", popular sushi wraps. Monostroma oligosaccharides with degree of polymerization 6 prepared by agarase digestion from Monostroma nitidum polysaccharides have been shown to be an effective prophylactic agent during in vitro and in vivo tests against Japanese encephalitis viral infection. The sulfated oligosaccharides from Monostroma seem to be promising candidates for further development as antiviral agents. The genus Monostroma is the most widely cultivated genus among green seaweeds.
Dictyota is a genus of brown seaweed in the family Dictyotaceae. Species are predominantly found in tropical and subtropical seas, and are known to contain numerous chemicals (diterpenes) which have potential medicinal value. As at the end of 2017, some 237 different diterpenes had been identified from across the genus.
