中文摘要: 为筛选出发酵玫瑰香葡萄酒效果最佳的粟酒裂殖酵母菌株,该试验首先通过不同发酵温度(23、25、28℃)和不同接菌量(1×106、5×106、1×107CFU/mL)对玫瑰香葡萄进行发酵,优选出适用于粟酒裂殖酵母的最适发酵温度和最适接菌量。然后利用前期根据发酵动力学试验筛选出的16株粟酒裂殖酵母对玫瑰香葡萄进行单独发酵。结果表明:适合粟酒裂殖酵母的发酵温度为25℃,接菌量为5×106CFU/mL。相较于其他发酵菌株,筛选出的粟酒裂殖酵母Sp-410单独发酵玫瑰香葡萄酒的苹果酸的降解率(97.98%)和色度值(1.26)最高,乙酸含量(0.18 g/L)和乙醛含量(48.46 mg/L)最低,因此,优选出的粟酒裂殖酵母菌Sp-410为酿造优质玫瑰香葡萄酒的优良菌种。
Abstract:To screen out the best strain of Schizosaccharomyces pombe for Muscat wine fermentation,this study first optimized the fermentation conditions including fermentation temperature(23,25℃and 28℃)and yeast inoculation amount(1×106,5×106CFU/mL and 1×107CFU/mL).Then,16 strains of S.pombe,which were screened out according to their fermentation kinetics,were used to independently ferment Muscat grapes.The results showed that the optimum fermentation conditions for S.pombe was 25℃and the yeast inoculation amount of 5×106CFU/mL.Compared with other strains,strain Sp-410 had the highest malic acid degradation rate(97.98%)and chromaticity value(1.26)and the lowest content of acetic acid(0.18 g/L)and acetaldehyde(48.46 mg/L).Therefore,strain Sp-410 was selected for its excellent performance in producing high-quality Muscat wine.
