Abstract

Several yeast colonies were isolated from wild flowers collected from East, West and South coast areas of Korea by plating of flower suspensions on the YPD plates containing antibiotics, streptomycin and ampicillin. Polymerase chain reactions (PCR) were performed for the amplification of D1/D2 region of 26S rDNA for those colonies. PCR-amplified nucleotide sequences were compared using BLAST for their identification. As results, 27 yeast strains belonged to 15 species were isolated from wild flowers collected at Donghae, where is located in eastern coast of Korea. Also, 34 strains belonged to 17 species were isolated from wild flowers of Daecheon, where is located in western coast of Korea. In addition, 22 strains belonged to 13 species were isolated from wild flowers collected at Wando, where is located in southern coast of Korea. Among those 45 species isolated from 3 different collection sites, only 4 species including Cryptococcus laurentii, Metschnikowia koreensis, Pseudozyma rugulosa, and Rhodotorula mucilaginosa were found from all 3 different collection sites. And 5 species including Cryptococcus aureus, Cryptococcus flavus, Hanseniaspora uvarum, Pichia guilliermondii, and Rhodosporidium fluviale were overlapped from the at least 2 different collection sites. Other 23 species were found only in a specific collection sites implying that each area has distinctive yeast flora.
