Abstract

Several kinds of yeasts were isolated from wild flowers collected from Muju resort of Deogyu mountain in Korea and identified by comparison of nucleotide sequences of D1/D2 region of 26S rDNA using BLAST. Totally twenty-two strains of eight species were isolated and Cryptococcus magnus (9 strains) and Cryptococcus flavescenes (6 strains) were dominant species. The supernatant and cell-free extracts were prepared and their antioxidant activity, anti-gout xanthine oxidase inhibitory activity and whitening tyrosinase inhibitory activity were investigated. Anti-gout xanthine oxidase inhibitory activities of Sporobolomyces phaffii JS00583 and Rhodotorula graminis JS00581 were 40.4% and 39.1%, respectively and also was 36.1% whitening tyrosinase inhibitory activity in the supernatant of Cryptococcus magnus JS00570.

덕유산 무주 리조트 일대에서 수집한 야생화 27점에서 효모 8종 22균주를 분리 동정하였다. 이들 균주 중에서 Cryptococcus magnus 9균주, Cryptococcus flavescens 6균주와 Cryptococcus sp. 2균주 등 Cryptococcus속 균들이 가장 많이 분리되었다. 이들 22균주들을 YPD 배지에서 24시간 배양하여 각각의 배양 상등액과 무세포 추출물을 제조한 후 이들의 항산화 활성과 항통풍성 xanthine oxidase 저해활성 등의 생리기능성들을 측정한 결과, Sporobolomyces phaffii JS00583과 Rhodotorula graminis JS00581의 배양 상등액이 각각 40.4%와 39.1%의 항통풍성 xanthine oxidase 저해활성을 보였다. 또한 Cryptococcus magnus JS00570의 상등액 역시 36.1%의 미백성 tyrosinase 저해활성을 보였다.
