Botryococcus Braunii
''Botryococcus braunii'' is a green, pyramid-shaped planktonic microalga that is of potentially great importance in the field of biotechnology. Colonies held together by a lipid biofilm matrix can be found in temperate or tropical oligotrophic lakes and estuaries, and will bloom when in the presence of elevated levels of dissolved inorganic phosphorus. The species is notable for its ability to produce high amounts of hydrocarbons, especially oils in the form of Triterpenes, that are typically around 30–40% of their dry weight. Compared to other green alge species it has a relatively thick cell wall that is accumulated from previous cellular divisions; making extraction of cytoplasmic components rather difficult. Much of the useful hydrocarbon oil is outside of the cell. Optimal growth environment ''Botryococcus braunii'' has been shown to grow best at a temperature of 23 °C, a light intensity of 60 W/m2, with a light period of 12 hours per day, and a salinity of 0.15 molar ...

Nordal Wille
Johan Nordal Fischer Wille (28 October 1858 – 4 February 1924) was a Norwegian botanist. He was a professor at the Royal Frederick University from 1893 to his death, founded the laboratory at the University Botanical Garden and co-founded the Natural History Museum. Personal life Wille was born in Hobøl as the son of physician Hans Georg Wille (1803–1879) and his wife Ingeborg Fischer (1811–1875). He was a grandnephew of priest and writer Hans Jacob Wille. He married three times. The first marriage with Anne Koller, a daughter of Carl Theodor Fredrik Koller, lasted from September 1891 to her death in March 1908. During this period he was a brother-in-law of Rasmus Meyer and Gustav Guldberg, who were married to two of Anne's sisters. The second marriage with Ragna Margrethe Knudsen lasted from September 1911 to her death in July 1917, and finally he married Swedish-born school teacher Ester Victoria Svensson in October 1918. Career Wille grew up in Hobøl, but eventually ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Botryococcus
''Botryococcus'' is a genus of green algae. The cells form an irregularly shaped aggregate. Thin filaments connect the cells. The cell body is ovoid, 6 to 10 μm long, and 3 to 6 μm wide. Fossils of the genus are known since Precambrian times, and form the single largest biological contributor to crude oil, and are a major component of oil shales. Description Appears as colonies of cells irregularly arranges cells in a folded mucilage. Cells spherical or oval, chloroplast net-like with a single pyrenoid.Guiry, M.D., John, D.M., Rindi, F. and McCarthy, T.K (Ed) 2007.

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opi ...

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 oth ...

National Center For Biotechnology Information
The National Center for Biotechnology Information (NCBI) is part of the United States National Library of Medicine (NLM), a branch of the National Institutes of Health (NIH). It is approved and funded by the government of the United States. The NCBI is located in Bethesda, Maryland, and was founded in 1988 through legislation sponsored by US Congressman Claude Pepper. The NCBI houses a series of databases relevant to biotechnology and biomedicine and is an important resource for bioinformatics tools and services. Major databases include GenBank for DNA sequences and PubMed, a bibliographic database for biomedical literature. Other databases include the NCBI Epigenomics database. All these databases are available online through the Entrez search engine. NCBI was directed by David Lipman, one of the original authors of the BLAST sequence alignment program and a widely respected figure in bioinformatics. GenBank NCBI had responsibility for making available the GenBan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
