Pichia pastoris

Pichia pastoris is a species of methylotrophic yeast. It was found in the 1960s, with its feature of using methanol, as a source of carbon and energy. After years of study, P. pastoris was widely used in Biochemical research and Biotech industries. With strong potential for being an expression system for protein production, as well as being a model organism for genetic study, P. pastoris has become important for biological research and biotech applications. In the last decade, some reports reassigned P. pastoris to the genus Komagataella with phylogenetic analysis, by genome sequencing of P. pastoris. The species was split into K. phaffii, K. pastoris, and K. pseudopastoris.
