Saccharomyces Castellii
''Saccharomyces'' is a genus of fungi that includes many species of yeasts. ''Saccharomyces'' is from Greek σάκχαρον (sugar) and μύκης (fungus) and means ''sugar fungus''. Many members of this genus are considered very important in food production. It is known as the brewer's yeast or baker's yeast. They are unicellular and saprotrophic fungi. One example is ''Saccharomyces cerevisiae'', which is used in making bread, wine, and beer, and for human and animal health. Other members of this genus include the wild yeast ''Saccharomyces paradoxus'' that is the closest relative to ''S. cerevisiae'', ''Saccharomyces bayanus'', used in making wine, and ''Saccharomyces cerevisiae'' var. ''boulardii'', used in medicine. Morphology Colonies of ''Saccharomyces'' grow rapidly and mature in three days. They are flat, smooth, moist, glistening or dull, and cream in color. The inability to use nitrate and ability to ferment various carbohydrates are typical characteristics of ''Sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Franz Meyen
Franz Julius Ferdinand Meyen (28 June 1804 – 2 September 1840) was a Prussian physician and botanist. Meyen was born in Tilsit, East Prussia. In 1830 he wrote ''Phytotomie'', the first major study of plant anatomy. Between 1830 and 1832, he took part in an expedition to South America on board the ''Prinzess Luise'', visiting Peru and Bolivia, describing species then new to science such as the Humboldt penguin. From 1823 to 1826, he studied medicine at the University of Berlin, followed by service as a military surgeon at the Charité in Berlin. In 1834 he became an associate professor of botany in Berlin. With Heinrich Friedrich Link, he was co-editor of the journal ''Jahresberichte über die Arbeiten für physiologische Botanik'' (1837–1839).Max Planck Institute for the History of Science, Berlin< ...

Saccharomyces Mikatae
''Saccharomyces mikatae'', a type of yeast in the ''Saccharomyces sensu stricto'' complex. Its type strain is NCYC 2888T. The cells are round to short-oval in shape, they arrange singly, in pairs and short-chain. Their budding Budding or blastogenesis is a type of asexual reproduction in which a new organism develops from an outgrowth or bud due to cell division at one particular site. For example, the small bulb-like projection coming out from the yeast cell is kno ... is multipolar.

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ca ...

Fungi
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a 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 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 group of related organisms, named the ''Eumycota'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), 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 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 ...

Saccharomyces Zonatus
''Saccharomyces'' is a genus of fungi that includes many species of yeasts. ''Saccharomyces'' is from Greek σάκχαρον (sugar) and μύκης (fungus) and means ''sugar fungus''.

Saccharomyces Uvarum
''Saccharomyces uvarum'' is a species of yeast that is commonly found in fermented beverages, particularly those fermented at colder temperatures. It was originally described by Martinus Willem Beijerinck in 1898, but was long considered identical to '' S. bayanus''. In 2000 and 2005, genetic investigations of various ''Saccharomyces'' species indicated that ''S. uvarum'' is genetically distinct from ''S. bayanus'' and should be considered a unique species. It is a bottom-fermenting yeast, so-called because it does not form the foam on top of the wort that top-fermenting yeast Yeasts are eukaryotic, single-celled microorganisms classified as members of the fungus kingdom.

Saccharomyces Pastorianus
''Saccharomyces pastorianus'' is a yeast used industrially for the production of lager beer, and was named in honour of Louis Pasteur by the German Max Reess in 1870. This yeast's complicated genome appears to be the result of hybridisation between two pure species in the ''Saccharomyces'' species complex, a factor that led to difficulty in establishing a proper taxonomy of the species. The now-defunct synonym ''Saccharomyces carlsbergensis'' was and continues to be used in scientific literature, but is invalid, as the name ''Saccharomyces pastorianus'' (Reess 1870) has taxonomic precedence. The name ''S. carlsbergensis'' is typically attributed to Emil Christian Hansen from the era when he worked for the Danish brewery Carlsberg in 1883, but in actuality it was not officially described by Hansen as a distinct species until 1908, along with another synonym, ''Saccharomyces monacensis.'' The type strains of both synonyms are currently stored in yeast banks under the taxonomic na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
