Pichia Methanolica
''Ogataea methanolica'' is a homothallic haploid organism that offers many of the advantages of a eukaryotic expression system such as protein processing and protein folding, while being as easy to manipulate as ''E. coli'' or ''Saccharomyces cerevisiae''. It is faster, easier, and less expensive to use than other eukaryotic expression systems such as baculovirus or mammalian tissue culture, and generally gives higher expression levels. As a yeast, it shares the advantages of molecular and genetic manipulations with Saccharomyces, and it has the added advantage of 10- to 100-fold higher heterologous protein expression levels. These features make ''P. methanolica'' very useful as a protein expression system.http://tools.invitrogen.com/content/sfs/manuals/pichiameth_man.pdf References External links {{Taxonbar, from=Q10607931 Saccharomycetaceae Yeasts Fungi described in 1974 ...

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] |
Saccharomycetales
Saccharomycetales belongs to the kingdom of Fungi and the division Ascomycota. It is the only order in the class Saccharomycetes. There are currently 13 families recognized as belonging to Saccharomycetales. GBIF also includes; Alloascoideaceae (with 5 genera), Eremotheciaceae (16) Trigonopsidaceae (with 36) and Wickerhamomycetaceae (with 141 genera). Genera ''incertae sedis'' According to The Mycota, genera included in the order, but of uncertain taxonomic position (''incertae sedis'') include '' Ascobotryozyma'' , '' Babjeviella'', '' Botryozyma'', '' Candida'' pro parte, '' Citeromyces'', '' Coccidiascus'', '' Komagataella'', ''Kuraishia'', '' Macrorhabdus'' (2), '' Nadsonia'' , '' Nakazawaea'', '' Pachysolen'', '' Peterozyma'', '' Schizoblastosporidon'' , ''Sporopachydermia'', and '' Trigonopsis''.

Pichiaceae
The Pichiaceae are a family of yeasts in the order Saccharomycetales. According to the 2007 Outline of Ascomycota, the family contains four genera, but GBIF lists 15 genera. The family was named by Zender in 1925. Genera As listed by GBIF; * '' Allodekkera'' (2) * ''Brettanomyces'' (5) * '' Byrrha'' * ''Dekkera'' (23) * '' Enteroramus'' * ''Hansenula'' (7) * ''Issatchenkia'' (37) * ''Komagataella'' (21) * '' Kregervanrija'' (7) * '' Martiniozyma'' (5) * '' Nakazawaea'' (31) * '' Phaffomyces'' (6) * ''Pichia ''Pichia'' (''Hansenula'' and ''Hyphopichia'' are obsolete synonyms) is a genus of yeasts in the family Pichiaceae with spherical, elliptical, or oblong acuminate cells.

Ogataea
''Ogataea'' is a genus of ascomycetous yeasts in the family Saccharomycetaceae. It was separated from the former genus '' Hansenula'' via an examination of their 18S and 26S rRNA partial base sequencings by Yamada et al. 1994.Y. Yamada, K. Maeda, K. Mikata: ''The phylogenetic relationships of the hat-shaped ascospore-forming, nitrate-assimilating Pichia species, formerly classified in the genus Hansenula Sydow et Sydow, based on the partial sequences of 18S and 26S ribosomal RNAs (Saccharomycetaceae): the proposal of three new genera, Ogataea, Kuraishia, and Nakazawaea.'' Bioscience, Biotechnology, and Biochemistry 58, 1994, 1245–1257. . The genus name of ''Ogataea'' is in honour of Koichi Ogata (x - 1977), who was a Japanese microbiologist from the Department of Agricultural Chemistry, Faculty of Agriculture, at Kyoto University. It was stated in the journal; "The genus is named in honor of the late Professor Dr. Koichi Ogata, Department of Agricultural Chemistry, Faculty of Agr ...

Saccharomycetaceae
The Saccharomycetaceae are a family of yeasts in the order Saccharomycetales that reproduce by budding. Species in the family have a cosmopolitan distribution, and are present in a wide variety of habitats, especially those with a plentiful supply of carbohydrate sources. The family contains the species ''Saccharomyces cerevisiae'', perhaps the most economically important fungus. Genera According to the 2007 Outline of Ascomycota, 20 genera are within the family, although for several of these (marked with a question mark below), the placement is uncertain and requires more study.

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. 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 calle ...
