We isolated 120 strains of wild yeasts from the water and riverside soils of Daejeoncheon and Gapcheon in Daejeon, Korea. We identified Debaryomyces udenii JSF601, Kazachstania telluris JSF602, Trichosporon faecale JSF614, Candida infanticola WJSL0039, Candida palmioleophila WJSL0048, Pichia spartinae WJSL0087, and Trichosporon coprophilum WJSL0093 from Daejeoncheon, and Leucosporidium golubevii WJSL0108 and Ustilentyloma graminis WJSL0118 from Gapcheon, as newly recorded yeast strains in Korea and investigated their microbiological characteristics. All of these previously unrecorded yeasts were oval- or ellipsoidal-shaped with ascospores, except C. infanticola WJSL0039, C. palmioleophila WJSL0048, and D. udenii JSF601. L. golubevii WJSL0108 and U. graminis WJSL0118 grew in vitamin-free medium, and C. infanticola WJSL0039 was halotolerant and grew in 10% NaClcontaining YPD broth. K. telluris JSF602 and P. spartinae WJSL0087 were thermophilic yeasts, which grew at 37 Celsius.
