Abstract

Yeasts isolated from wild flowers of Gyejoksan in Daejeon city, Oseosan in Chungchungnamdo, and Baekamsan in Jeollabukdo, Korea were identified by comparison of nucleotide sequences for PCR-amplified D1/D2 region of 26S rDNA or internal transcribed spacer (ITS) 1 and 2 including 5.8S rDNA using BLAST. Twelve yeast strains of ten species and seventeen yeast strains of ten species were isolated from wild flowers of Gyejoksan and Oseosan, respectively. And thirty seven yeast strains of twenty four species were isolated from wild flowers of Baekamsan. Total thirty four yeast species were isolated from three different sample collection areas, but only nine species were overlapped from the at least two different sampling areas: Cryptococcus sp., Cryptococcus aureus, Cryptococcus flavescens, Cryptococcus flavus, Metschnikowia sp., Pseudozyma aphidis, Rhodotorula glutinis, Sporobolomyces carnicolor, and Sporobolomyces ruberrimus. Among them only Cryptococcus aureus was occurred from all three different collection sites. Other twenty five species were restricted to specific collection site suggesting that each area has distinctive yeast flora.

국내 자연환경의 효모 균총을 확인함으로써 유용한 효모자원을 확보하기 위한 연구의 일환으로 대전 계족산, 충남 오서산 그리고 전북 백암산 지역에 서식하는 야생화들을 채집하여 이들로부터 효모들을 분리, 동정하였다. 대전의 계족산에서 수집한 야생화로부터는 10종에 속하는 12균주의 효모들을 분리하였고, 충남의 오서산에서 수집한 야생화로부터는 10종의 효모들 17균주를 분리하였다. 또한 전북 백암산의 야생화로부터 모두 24종에 속하는 38균주의 효모들을 분리하였다. 계족산, 오서산, 그리고 백암산에서 모두 발견된 효모는 Cryptococcus 속, Pseudozygoma 속, Rhodotorula 속, Sporobolomyces 속에 속하는 9종의 효모들이었다. 특히 3개 지역에서 수집한 야생화들로부터 Cryptococcus 속에 속하는 Cryptococcus aureus만이 모두 분리되었는데, 이 결과는 각 지역마다 독특한 효모 다양성을 보이고 있음을 시사하는 것이다.
