In the current study, we have isolated and identified 4 wild ascomycetous yeasts from the soil samples collected from Nowon-gu, Seoul city, South Korea. One yeast strain isolated from the soil samples belonging to the order Saccharomycetales is unrecorded strain in the South Korea. The D1/D2 region of the 26S rRNA gene sequence of the isolated strain is analyzed with closely related reference strains using the Basic Local Alignment Search Tool (BLAST). The biochemical characteristics of the yeast strain was tested using an API 20C AUX kit, and the morphological characteristics of the cell was observed using the phase contrast microscope. This strain was assigned to the phyla Ascomycota in the order Saccharomycetales. The yeast strain GR9, belong to the genus Starmerella. The strain had oval-shaped and polar budding cells. This research focuses on the morphological and biochemical properties of one unrecorded yeast species that have not been officially record in Korea.
