Freshwater ecosystems are significant habitats of fungi including yeasts. This study aimed to isolate and characterize wild yeasts from freshwater environments in Korea. The yeast isolates were identified by using the D1/D2 domains of the 26S rDNA regions. We identified four strains, Candida viswanathii (NNIBRFG39781), Curvibasidium cygneicollum (NNIBRFG49003), Oberwinklerozyma silvestris (NNIBRFG39803) and Vishniacozyma foliicola (NNIBRFG6120). These yeasts had not previously been recorded in Korea. We investigated the morphological and cultural characteristics of these yeasts. All of them grew on YPD, PD and YM media. Candida viswanathii (NNIBRFG39781), O. silvestris (NNIBRFG39803) and V. foliicola (NNIBRFG6120) grew in YPD medium containing glucose and in pH range of 4-8. Curvibasidium cygneicollum (NNIBRFG49003) grew well low temperature compared to others and slowly.
