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.
