Pichia (Hansenula and Hyphopichia are obsolete synonyms) is a genus of yeasts in the family Pichiaceae with spherical, elliptical, or oblong acuminate cells. Pichia is a teleomorph , and forms hat-shaped, hemispherical, or round ascospores during sexual reproduction.

Hansenula polymorpha: A Model Organism for Fundamental Studies. Hansenula polymorpha occurs naturally in spoiled orange juice, maize meal, the gut of various insect species, and soil. Hansenula polymorpha (also designated as P. angusta, Ogataea angusta) is the widest known member of Hansenula genus. Taxonomy

The methylotrophic yeast Hansenula polymorpha, known as a non-conventional yeast, is used for the last 30 years for the production of recombinant proteins, including enzymes, vaccines, and biopharmaceuticals.

The genus Pichia (formerly Hansenula) contains Ascomycete yeast species from the Saccharomycetaceae family. For many years, the phylogenetic location of this genus was widely discussed, and some taxonomic changes occurred when DNA analyses were used (Irzykowska and Waśkiewicz, 2014).

Wickerhamomyces anomalus has been previously classified as Hansenula anomala, Pichia anomala, and Candida pelliculosa and was recently reclassified in the genus Wickerhamomyces after phylogenetic analysis of its genetic sequence.

Methylotrophic yeast species (e.g. Hansenula polymorpha, Pichia pastoris) can grow on methanol as sole source of carbon and energy. These organisms are important cell factories for the production of recombinant proteins, but are also used in ...

The methylotrophic yeast Ogataea polymorpha (syn. Hansenula polymorpha or Pichia angusta) is one of the most important industrially applied non-conventional yeasts [1, 2]. O. polymorpha is a ubiquitous yeast species occurring naturally in spoiled orange juice, maize meal, in the gut of various insect species and in soil.

Mar 20, 2018 · Distinguishing Features: Distinguished from some other strains of Pichia (Hansenula) by high osmotolerance, ferments sucrose, assimilates raffinose, not L-rhamnose (Kurtzman 1998). Role in wine: Normal grape flora, active …

Nov 27, 2013 · Hansenula polymorpha DL1 is a methylotrophic yeast, widely used in fundamental studies of methanol metabolism, peroxisome biogenesis and function, and also as a microbial cell factory for production of recombinant proteins and metabolic engineering towards the goal of high temperature ethanol production.

May 1, 2019 · The methylotrophic yeast Hansenula polymorpha, known as a non-conventional yeast, is used for the last 30 years for the production of recombinant proteins, including enzymes, vaccines, and biopharmaceuticals.
