Isolation and Identification of Wild Yeasts from Soils of an Herb Park in Seoul Metropolitan City and Characteristics of Unrecorded Yeasts

Abstract

This study focused on the isolation of wild yeasts from the soils of an herb park in Seoul, Korea, and characterization of unrecorded yeasts. Fifteen yeast strains of nine species were isolated and identified. Among them, strains of the Cryptococcus genus, such as Cryptococcus laurentii (2 strains), Cryptococcus saitoi (two strains), Cryptococcus podzolicus (2 strains), and Cryptococcus sp. (2 strains) were dominant. Candida boleticola SU14-2, Candida novakii SU6-2 and Cryptococcus podzolicus SU18-3 were also screened as newly recorded yeasts in Korea. Candida novakii SU6-2 formed ascospores and a pseudomycelium, and Candida boleticola SU14-2 grew well in the 5% NaCl-containing yeast extract-peptone-dextrose medium.
