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.

Two unrecorded yeasts, Meyerozyma caribbica UL5-1 and Pichia silvicola UL6-1 were screened from 58 yeasts which were isolated from wild flowers in Ulleungdo in Gyeongsangbuk-do, Korea. The morphological and cultural characteristics of these unrecorded yeasts were investigated. Both yeasts were oval in shape and formed pseudomycelia. P. silvicola UL6-1 formed ascospore, but M. UL5-1 did not. P. silvicola UL6-1 and M. caribbica UL5-1 also grew in vitamin-free medium and 5% NaCl-containing yeast extract-peptone-dextrose medium. The two unrecorded yeasts assimilated glucose, galactose, xylose, cellobiose, trehalose, glycerol and sorbitol, and also fermented glucose, fructose and mannose. The supernatant of both M. caribbica UL5-1 and P. silvicola UL6-1 showed high antihypertensive angiotensin I-converting enzyme inhibitory activity of 84.2% and 82.6%, respectively. Cell-free extract of P. silvicola UL6-1 also showed very high anti-diabetic ${\alpha}$-glucosidase inhibitory activity (85.8%).

Several types of yeasts were isolated from wild flowers around Jangseong Lake in Jeollanam-do, Republic of Korea and identified by comparing the nucleotide sequences of the PCR amplicons for the D1/D2 variable domain of the 26S ribosomal DNA using Basic Local Alignment Search Tool (BLAST) analysis. In total, 60 strains from 18 species were isolated, and Pseudozyma spp. (27 strains), which included Pseudozyma rugulosa (7 strains) and Pseudozyma aphidis (6 strains), was dominant species. Among the 60 strains, Bullera coprosmaensis JS00600 represented a newly recorded yeast strain in Korea, and its microbiological characteristics were investigated. The yeast cell has an oval-shaped morphology measuring $1.4{\times}1.7{\mu}m$ in size. Bullera coprosmaensis JS00600 is an asporous yeast that exhibits no pseudomycelium formation. It grew well in vitamin-free medium as well as in yeast extract-malt extract broth and yeast extract-peptone-dextrose (YPD) broth, and it is halotolerant growing in 10% NaCl-containing YPD broth.

국내 자연환경으로부터 다양한 효모들을 분리, 동정하고 나아가 이들로부터 유용물질을 생산하는 효모자원을 확보하기 위한 연구의 일환으로 우리나라 동해안, 서해안, 남해안에 서식하는 야생화들을 채집하여 이들로부터 효모들을 분리한 후 분자생물학적 방법으로 동정하였다. 동해시에서 수집한 야생화로부터는 Candida silvae 등을 포함한 15종에 속하는 27균주의 효모들을 분리하였다. 서해안의 대천시 해수욕장 주위 야생화에서는 Bulleromyces albus를 비롯한 17종 34균주가 분리, 동정되었다. 또한 남해안의 완도군 대문리 주위의 야생화들로부터는 Cryptococcus flavus를 포함하여 13종에 속하는 효모 22 균주들이 분리 동정되었다. 전체적으로 우리나라 동해안, 서해안, 남해안의 야생화로부터 모두 45종에 속하는 효모들 83균주를 분리, 동정하였다.

Among 80 types of yeast isolated from wild flowers in Daejeon, Korea, two species that have not yet been identified by phylogenetic analysis of the internal transcribed spacer-2 (ITS2) genes and 26S rDNA sequences were identified as Candida sp. 44-C-1 and Cryptococcus sp. 9-D-1. Neither of the newly identified species formed ascospores, while Candida sp. 44-C-1 formed pseudomycelium and Cryptococcus sp. 9-D-1 did not.

This study was conducted from September 1, 1994 to December 12, 1994 to investigate the leaf color characteristics, flowering period and fruit period of Wild plants in Suwon and Taejon area. The results were as follows; 1. By using the chlorophyll meter, the chlorophyll content of Liriope platyphylla, Trifolium repens, Dystaenia takeshimana was 30.0, 22, 2 and 19.0, respectively on December 9, 1994. 2. By leaf color based on KBS standard color number, Liriope piatyphylla, Trifolium repens, Dvstoenia takeshirnana were green till December 9, 1994. 3. The flowers of Aster sea ber, Atractylodes japonica, Allium thunbergii, Liriope platyphylla, Scilla scilloides, Digitaria sanguinalis, Sanguisorba officinalis were persisting till September, and the flowers of Crysanthemum boreale were persisted till November and Allium thunbergii, till October.

Research was initiated to investigate vegetation coverage and growth of main herbaceous flowers under low maintenance condition like a wild state. Eleven entries were comprised of 1 annual, 2 biennials and 8 perennials from widely used herbaceous flowers in Korea. Vegetation coverage and germination rate were high on annual and biennials when compared to perennials. Callistephus chinensis showed high vegetation coverage but lasted only for a year in 2001 and disappeared in 2002 as an annual. Oenothera odorata and Oenothera lamarckiana were also high vegetation coverage species with persistent only for two years as biennials. Therefore, these species should not be used in a large amount for ecological restoration when mixed with perennials because of affecting the vegetation coverage of perennials. There were considerable variations in vegetation coverage with perennial herbaceous flowers : Lotus corniculatus and Taraxacum platycarpum-high vegetation coverage species, Platycodon grandiflorum, Aster tataricus and Aster koraiensis-medium vegetation coverage species, and Aster yomena, Patrinia scabiosaefolia and Chrysanthemum indicum-low vegetation coverage species. Growth types of herbaceous flowers tested in this research were divided into 4 types : Callistephus chinensis, Oenothera lamarckiana and Aster koraiensis-wide leaf and tall type, Aster tataricus, Patrinia scabiosaefolia, Oenothera odorata, Taraxacum platycarpum, and Aster yomena-medium leaf and medium tall type, Platycodon grandiflorum-fine leaf and dwarf type, and Lotus corniculatus-fine leaf and tall type.

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.
