Komagataella kurtzmanii is a species of ascomycete fungi existing as a yeast.
Discovery
Komagataella kurtzmanii was first described from a strain that had been previously collected from a fir tree (Abies sp.) in the Catalina mountains, in Arizona.[1] It was determined to be a distinct species on the basis of comparisons of DNA sequences. K. kurtzmanii is named after Cletus P. Kurtzman, for his contributions to the study of yeast taxonomy.[1]
Growth and morphology
When grown on malt extract agar, cells of K. kurtzmanii have been described as "spherical... to oviod" with lengths ranging from 2-7 μm.[1] Within asci, growth of 1-4 hat-shaped ascospores has been reported. Growth does not occur at temperatures of 35°C or above.[1][2] Glucose is fermented by K. kurtzmanii; other common carbohydrates are not fermented.[1] K. kurtzmanii is unique among Komagataella as the only member unable to assimilate trehalose.[1]
Phylogeny
Within Komagataella, K. kurtzmanii is most closely related to K. phaffii.[1][3][2]
