Abstract

Film-formation, which often occurs during storage of apple wine, owing to contamination by film-forming yeasts, results in inferior products. Therefore, for the purpose of preventing this occurrence, we isolated and identified yeast strain. Among the total number of 45 yeast strains which were isolated from contaminated apple wine in winery, the strains FY-4 and FY-5 were found to be useful. The strain FY-5, which greatly formed film on apple wine, was identified as Hansenula beijerinckii or similar strain according to taxonomic characteristics.

저장(貯藏)사과주의 산막(産膜)을 방지(防止)할 목적(目的)으로 사과주 양조장내(釀造場內)의 산막(産膜)이 형성(形成)된 저장(貯藏) 사과주에서 산막효모(産膜酵母) 45종(種)을 분리(分離)하고 그중(中) 가장 뚜렷한 산막생성능(産膜生成能)을 나타내는 균주(菌株) FY-4, FY-5를 선별(選別)하였다. 2균주(菌株) 중(中) FY-5는 분류학적(分類學的) 제성질(諸性質)로 보아 Hansenula beijerinckii 또는 그 근연균(近緣菌)으로 동정(同定)되었다.
