Abstract

경상북도 울릉도와 경상남도 욕지도의 야생화들에 분포하고 있는 효모 종 다양특성을 알아보고자 이들로부터 효모를 분리하고 분자생물학적인 26S rDNA의 D1/D2 영역 염기서열을 확인, 비교하여 동정하였다. 울릉도 야생화들에서는 22종 48균주, 욕지도에서 야생화들로부터는 25종 60균주 효모들을 분리, 동정하였다. 두 섬에서 분리한 효모들 중 Cryptococcus albidus, Cryptococcus laurentii, Metschnikowia reukafii, Pichia scolyti, Rhodotorula glutinis, Rhodotorula graminis and Rhodotorula mucilaginosa 등 7종이 공통으로 분리되었고 나머지 33종이 두 섬에서 특이적으로 분리되었다. Various yeasts from wild flowers of Ulleungdo in Gyeongsangbuk-do and Yokjido in Gyeongsangnam-do, Korea were isolated and identified by comparison of nucleotide sequences for PCR-amplified D1/D2 region of 26S rDNA using BLAST. Forty eight yeast strains of twenty two species and sixty yeast strains of twenty five species were isolated from wild flowers of Ulleungdo and Yokjido, respectively. Only seven species were overlapped from the two different islands areas: Cryptococcus albidus, Cryptococcus laurentii, Metschnikowia reukafii, Pichia scolyti, Rhodotorula glutinis, Rhodotorula graminis and Rhodotorula mucilaginosa. Among forty species from two different islands, other thirty three species were restricted to specific collection site suggesting that each area has distinctive yeast flora.
