'''''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.<ref name="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. {{doi|10.1271/bbb.58.1245}}.</ref>
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 Agriculture, Kyoto University, Kyoto, Japan, in recognition of his studies on the oxidation and assimilation of methanol (C1 compound) in methanol-utilizing yeasts."<ref>{{cite book | last=Burkhardt | first=Lotte | title=Eine Enzyklopädie zu eponymischen Pflanzennamen |trans-title=Encyclopedia of eponymic plant names | publisher=Botanic Garden and Botanical Museum, Freie Universität Berlin | year=2022 | isbn=978-3-946292-41-8 | url=https://doi.org/10.3372/epolist2022|format=pdf |language=German |location=Berlin | doi=10.3372/epolist2022 | s2cid=246307410 |access-date=January 27, 2022}}</ref>
The genus was [[circumscription (taxonomy)|circumscribed]] by Yuzo Yamada, Kojiro Maeda and Kozaburo Mikata in Biosc., Biotechn. Biochem. vol.58 (Issue 7) on page 1253 in 1994.
== Diagnosis ==
Like other yeasts, also the species within the genus ''Ogataea'' are single-celled or build pseudohyphae of only a few elongated cells; true hyphae are not formed.<ref name="Kurtzman et al. 2011" />
They are able to reproduce sexually or asexually. The latter case happens with a cell division by multilateral budding on a narrow base with spherical to ellipsoidal budded cells. In the sexual reproduction the [[ascus|asci]] are deliquescent and may be unconjugated or show conjugation between a cell and its bud or between independent cells. Asci produce one to four, sometimes more, [[ascospore]]s which are hat-shaped, allantoid or spherical with a ledge. The species are homothallic or infrequently heterothallic.<ref name="Kurtzman et al. 2011" />
''Ogataea'' cells are able to ferment [[glucose]] or other sugars and some species assimilate [[nitrate]]. All known species are able to utilize [[methanol]] as carbon source. The predominant [[ubiquinone]] is coenzyme Q-7 and the diazonium blue B test is negative. Some species are used and cultured for microbiological and genetic research e.g. ''[[Ogataea polymorpha]]'', ''[[Ogataea minuta]]'' or ''[[Ogataea methanolica]]''.<ref name="Kurtzman et al. 2011" /> ''Ogataea minuta'' (Wickerham) Y. Yamada, K. Maeda & Mikata is the type species for this genus.<ref name="Yamada et al. 1994" /><ref name="Kurtzman et al. 2011" />
== Species ==
''Ogataea'' consists of several species and is placed within the [[Saccharomycetales]] as a sister genus to ''[[Ambrosiozyma]]''.  Following Kurtzman et al. 2011 the genus consists of 31 species but also shows, that there are several more within the [[taxon]] that are part of the polyphyletic genus ''[[Candida (fungus)|Candida]]''.<ref name="Kurtzman et al. 2011">Cletus P.
