The sequence of the D1/D2 domain of the large subunit rDNA gene revealed that the strain belonged to the genus Kazachstania and was phylogenetically related to a clade including Kazachstania aerobia, Kazachstania servazzii, Kazachstania solicola and Kazachstania unispora. The novel isolate differed from members of this clade in its ability to assimilate d-glucono-1,5-lactone and its very weak fermentation of glucose and sucrose; its assimilation profile was unique within the genus Kazachstania. Monosporal colonies were able to sporulate, indicating that the species is homothallic. It is proposed that the isolate represents a novel species, Kazachstania ichnusensis sp. nov., with LCF 1675T ( = CBS 11859T) as type strain. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.032243-0
