E. C. Hansen
Emil Christian Hansen (8 May 1842 – 27 August 1909) was a Danish mycologist and fermentation physiologist. Early life and education Hansen was born in Ribe to Joseph Christian Hansen, a house-painter, and his wife Ane Catherina Dyhre. Between 1874 and 1875 he edited and distributed an mycological exsiccata work, namely ''Fungorum fimicolorum exempl. exsiccati'', with 350 numbered specimen units. He was awarded a gold medal in 1876 for an essay on fungi, titled ''De danske Gjødningssvampe''. During his days as a university student in Copenhagen, he worked as an unpaid assistant to zoologist Japetus Steenstrup (1813–1897). Career In 1876, with Alfred Jørgensen (1848–1925), he published a Danish translation of Charles Darwin’s "The Voyage of the Beagle"; ''Rejse om Jorden''. From 1879 to 1909, he was director of the physiological department at Carlsberg Laboratory. Hired by the Carlsberg Laboratory in Copenhagen in 1879, he became the first to isolate a pure cell ...

Ribe
Ribe () is a town in south-west Jutland, Denmark, with a population of 8,367 (2025). It is the seat of the Diocese of Ribe. Until 1 January 2007, Ribe was the seat of both a surrounding municipality and county. It is now part of the enlarged Esbjerg Municipality in the Region of Southern Denmark. It is the oldest town in Denmark. History The town was a center of commercial activity in the early 8th century, and this may have originated with royal influence. Coins may have been struck there in 720. Whichever king was involved in the digging of the Kanhave Canal may have been involved in the establishment of Ribe also. Trade contacts were mostly with Frisia and England. Of the over 300 sceatas found in Denmark, 216 come from in or around Ribe, most of them were of the Frisian Wodan type, and these were likely minted in Ribe in the early eighth century. The Ancient Diocese of Ribe was established in 948 with the consecration of Leofdag of Ribe as its first bishop. Early in t ...

Sugar
Sugar is the generic name for sweet-tasting, soluble carbohydrates, many of which are used in food. Simple sugars, also called monosaccharides, include glucose Glucose is a sugar with the Chemical formula#Molecular formula, molecular formula , which is often abbreviated as Glc. It is overall the most abundant monosaccharide, a subcategory of carbohydrates. It is mainly made by plants and most algae d ..., fructose, and galactose. Compound sugars, also called disaccharides or double sugars, are molecules made of two bonded monosaccharides; common examples are sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (two molecules of glucose). White sugar is almost pure sucrose. In the body, compound sugars are hydrolysed into simple sugars. Longer chains of monosaccharides (>2) are not regarded as sugars and are called oligosaccharides or polysaccharides. Starch is a glucose polymer found in plants, the most abundant source of energy in human foo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yeasts
Yeasts are eukaryotic, single-celled microorganisms classified as members of the fungus kingdom. The first yeast originated hundreds of millions of years ago, and at least 1,500 species are currently recognized. They are estimated to constitute 1% of all described fungal species. Some yeast species have the ability to develop multicellular characteristics by forming strings of connected budding cells known as pseudohyphae or false hyphae, or quickly evolve into a multicellular cluster with specialised cell organelles function. Yeast sizes vary greatly, depending on species and environment, typically measuring 3–4 μm in diameter, although some yeasts can grow to 40 μm in size. Most yeasts reproduce asexually by mitosis, and many do so by the asymmetric division process known as budding. With their single-celled growth habit, yeasts can be contrasted with molds, which grow hyphae. Fungal species that can take both forms (depending on temperature or other cond ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Hanseniaspora
''Hanseniaspora'' is a genus of yeasts. The name ''Kloeckera'' is applied to its anamorph form. They are typically apiculate (lemon-shaped) in shape and often found in grape musts pre-fermentation. The genus name ''Hanseniaspora'' honours Emil Christian Hansen (1842–1909), who was a Danish mycologist and fermentation physiologist. It was initially circumscribed by H. Zikes in 1911, but not validly published. Albert Klöcker published the name validly the following year. The genus is notable for its loss of many highly conserved genes responsible for cell cycle regulation and genome integrity, resulting in increased evolution rates and genome size reduction. It can be divided into two lineages: a faster-evolving lineage (FEL) diversifying about 87 mya, and a slower one diversifying about 52 mya. The FEL has more of such gene losses, resulting in more dramatic changes in the genome and inactivation of multiple metabolic pathways. However, it has managed to diversify and thri ...

Binomial Authority
In taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Hom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
