Saccharomycodaceae
The Saccharomycodaceae are a family of yeasts in the order Saccharomycetales. According to the 2007 Outline of Ascomycota, the family contains four genera, although the placement of three of these (''Hanseniaspora'', '' Nadsonia'', and '' Wickerhamia'') is uncertain. Species in the family have a cosmopolitan distribution and are found in both temperate and tropical The tropics are the regions of Earth surrounding the Equator. They are defined in latitude by the Tropic of Cancer in the Northern Hemisphere at N and the Tropic of Capricorn in the Southern Hemisphere at S. The tropics are also referred to ... areas.

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 diversity and thrive ...

Saccharomycodes
''Saccharomycodes'' is a genus of yeasts. They are helobiallly reproducing yeasts. The type species is ''Saccharomycodes ludwigii''. The other species, ''Saccharomycodes sinensis'', is known from a single strain that was isolated from soil from a forest on Mount Chienfang on Hainan in China. It is the sister genus of ''Hanseniaspora''. Relationships with humans The species ''Saccharomycodes lugwigii'' is considered a "spoilage" yeast in the winemaking process and is commonly referred to as the "winemaker's nightmare". It has a high polluting capacity, beginning at one to two cells per liter. It has a high tolerance for sulfur dioxide, high sugar levels, and pressurized carbon dioxide and is difficult to eradicated from an already contaminated environment. It produces high levels of secondary metabolites, including isobutanol, amyl alcohol, and isoamyl alcohol Isoamyl alcohol is a colorless liquid with the formula , specifically (H3C–)2CH–CH2–CH2–OH. It is one of several ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungi
A fungus (plural, : fungi or funguses) is any member of the group of Eukaryote, eukaryotic organisms that includes microorganisms such as yeasts and Mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as a Kingdom (biology), kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of motility, mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ascomycota
Ascomycota is a phylum of the kingdom Fungi that, together with the Basidiomycota, forms the subkingdom Dikarya. Its members are commonly known as the sac fungi or ascomycetes. It is the largest phylum of Fungi, with over 64,000 species. The defining feature of this fungal group is the " ascus" (), a microscopic sexual structure in which nonmotile spores, called ascospores, are formed. However, some species of the Ascomycota are asexual, meaning that they do not have a sexual cycle and thus do not form asci or ascospores. Familiar examples of sac fungi include morels, truffles, brewers' and bakers' yeast, dead man's fingers, and cup fungi. The fungal symbionts in the majority of lichens (loosely termed "ascolichens") such as '' Cladonia'' belong to the Ascomycota. Ascomycota is a monophyletic group (it contains all descendants of one common ancestor). Previously placed in the Deuteromycota along with asexual species from other fungal taxa, asexual (or anamorphic) ascom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saccharomycetes
Saccharomycetes belongs to the Ascomycota division of the kingdom Fungi. It is the only class in the subdivision Saccharomycotina, the budding yeast 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 consti ...s. Saccharomycetes contains a single order, Saccharomycetales. Saccharomycetes are known for being able to comprise a monophyletic lineage with a single order of about 1,000 known species. These yeasts live as decomposers, feeding on dead and decaying wood, leaves, litter, and other organic matter. According to Suh et al. (2006), "yeasts are responsible for important industrial and biotechnological processes, including baking, brewing and synthesis of recombinant proteins," with Saccharomycetes being model organisms in research. Asia is likely to be the origin of the source. Reference ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genera
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. 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 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. phylogenetic analysis should ...

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 ...

Yeast
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. Yeasts are unicellular organisms that evolved from multicellular ancestors, with some species having the ability to develop multicellular characteristics by forming strings of connected budding cells known as pseudohyphae or false hyphae. 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 conditions) are ...
