Discovery
Komagataella populi was first described in 2012 from a sample taken in 1945 from Peoria, Illinois, from the sap of a cottonwood tree (Populus deltoides).[1]
Growth and morphology
Komagataella populi, when grown on YM agar, is white in color and has been described as spherical to ellipsoidal in shape, with sizes ranging from 2-6 μm.[1] Cells typically appear singly or in pairs. Cell division is performed via multilateral budding.[1] Ascospore formation is infrequent and results in hat-shaped ascospores.[1]
Komagataella populi is capable of fermentation of glucose, as well as weak fermentation of trehalose. It is unable to ferment many other common sugars.[1] It has been shown to use methanol and xylose as carbon sources more efficiently than other species of Komagataella.[2]
Phylogeny
Komagataella populi is believed to be most closely related to Komagataella pseudopastoris and Komagataella mondaviorum.[1][2][3]
