사과주(酒) 양조(釀造)에 적합(適合)한 우수효모(酵母)를 얻어 이를 이용(利用)하기 위하여 대전시(大田市) 및 기타(其他) 여러 지역(地域)에서 수집(蒐集)한 각종(各種) 시료과실중(試料果實中)에서 1,358주(株)의 효모(酵母)를 분리(分離)하고 이들 중(中)에서 SH-49, SH-129 및 SH-338의 3주(株)를 선정(選定)하여 이용면(利用面)과 균학적(菌學的) 성질(性質)에 관(關)한 시험(試驗)을 하였다. 시험결과(試驗結果)는 다음과 같다. 1. 선정(選定)된 SH-49 및 SH-129는 타균주(他菌株)에 비(比)하여 발효력(醱酵力), 생성(生性)사과주(酒)의 주질(酒質)및 아황산(亞黃酸) 내성시험등(耐性試驗等)에서 우수한 결과(結果)를 보였으며 특(特)히 SH-49가 우수하였다. 2. SH-49 및 SH-129를 사용(使用)하여 만든 사과주(酒)는 다른 균주(菌株)의 것에 비(比)하여 총산량(總酸量)이 약간 적었다. 3. SH-49 및 SH-129를 사용(使用)한 경우에는 사과주료가 주발효기간중(酒醱酵期間中)에 속(速)히 청징화(淸澄化) 되었다. 저장(貯藏) 45일후(日後)의 사과주(酒)의
Extensive selection works on wild yeasts of fruits were carried cut to obtain strains which are applicable to apple wine making. Among the total number of 1,358 yeast strains which were isolated from various fruit samples collected from the vicinity of Daejeon and other regions cf Korea, the strains SH-49, SH-129 and SH-338 were found to be useful. Then experiments on their morphological and physiological characteristics, and on the aspects of practical use in apple wine making were proceeded. The results obtained were as follows: 1. The strains SH-49 and SH-129, particularly SH-49, were appeared to have good fermentation ability, tolerance to sulfur dioxide and to produce fine quality of apple wine. 2. Apple wines made by using the strain, SH-49 and SH-129 contained less amount of total acids than those by other strains. 3. Apple wines of SH-49 and SH-129 were clarified rapidly during the primary fermentation period, and their absorbancy at 430 nm after 45 days of storage were approximately half of others. 4. Apple wine of SH-338 contained higher amount of residual sugar and its quality was superior to others. It is considered that this strain could be used in the production of apple wine of a characteristic quality. 5. The strains SH-49 and SH-338 were identified as a Saccharomyces cerevisiae according to Taxanomic Study of Yeasts by Lodder, however, classification of SH-129 was suspended for further study.
