摘要：
The present invention relates to Issatchenkia orientalis KCTC 12141BP (Korean Collection for Type Culture, accession date: February 21, 2012) having excellent acid resistance, sugar resistance, and alcohol resistance, and a fermented food using the same. As proved by examples of the present specification, Issatchenkia orientalis MS-1 having excellent flavor at the time of fermentation as well as excellent acid resistance, sugar resistance, and alcohol resistance according to the present invention is useful for the fermentation in a medium containing high-concentration organic acid since, unlike general yeasts, it exhibits growth of 88% or higher under acidic conditions of pH 2 as compared with pH 5.3 which is the optimum growth pH value, can grow under conditions of 0.4% oxalic acid and 0.4% acetic acid, and does not show growth inhibition even with the treatment with 1% or higher citric acid and maleic acid. Further, Issatchenkia orientalis MS-1 of the present invention can grow even under high-concentration sugar conditions of 40% or higher and thus achieve fermentation under hyperosmotic conditions such as honey, and can grow even under the treatment with 10% alcohol, unlike various Saccharomyces cerevisiae strains commercially used at the time of fermentation, and thus is useful for the fermentation under conditions requiring resistance against high-content alcohol. Further, Issatchenkia orientalis MS-1 of the present invention has excellent flavor at the time of fermentation and thus can be used for the production of enhanced functional fermented beverages and traditional foods. Therefore, the present invention is very useful in the fermented food industry.본 발명은 내산성, 내당성 및 내알코올성이 우수한 이사첸키아 오리엔탈리스(Issatchenkiaorientalis)KCTC 12141BP(Korean Collection for Type Culture, 수탁일자: 2012년 2월 21일)와 이를 이용한 발효 식품에 관한 것이다. 본 발명의 내산성, 내당성 및 내알코올성이 우수하면서도 발효시 풍미가 우수한 이사첸키아 오리엔탈리스 MS-1은, 본 명세서의 실시예를 통해 증명된 바와 같이 일반적인 효모들과는 달리, pH 2의 산성조건에서도 최적생육 pH인 pH 5.3에 비해 88% 이상의 생육도를 나타내며
