| Zusammenfassung: | <jats:p>During an investigation of yeast biota in the rhizosphere of lentisk in Sardinian semi-arid areas, a strain was isolated that could not be assigned to any known species. The sequence of the D1/D2 domain of the large subunit rDNA gene revealed that the strain belonged to the genus <jats:italic>Kazachstania</jats:italic> and was phylogenetically related to a clade including <jats:italic>Kazachstania aerobia</jats:italic>, <jats:italic>Kazachstania servazzii</jats:italic>, <jats:italic>Kazachstania solicola</jats:italic> and <jats:italic>Kazachstania unispora.</jats:italic> The novel isolate differed from members of this clade in its ability to assimilate <jats:sc>d</jats:sc>-glucono-1,5-lactone and its very weak fermentation of glucose and sucrose; its assimilation profile was unique within the genus <jats:italic>Kazachstania</jats:italic>. Monosporal colonies were able to sporulate, indicating that the species is homothallic. It is proposed that the isolate represents a novel species, <jats:italic>Kazachstania ichnusensis</jats:italic> sp. nov., with LCF 1675<jats:sup>T</jats:sup> ( = CBS 11859<jats:sup>T</jats:sup>) as type strain.</jats:p> |
