摘要 以魔芋飞粉蛋白酶解物为研究对象,利用静态激光光散射测定其分子量后,考察了其对酿酒酵母菌落大小、出芽率、菌体数量及代谢产物影响。实验结果表明添加6218u蛋白酶解物对酿酒酵母生长有明显的促进作用,培养液中还原糖转化率得以提高,乙醇含量明显增大。 In this study, the molecular weight of konjac powder protein hydrolysates was determined by static laser light scattering analysis in order to investigate the yeast colony size, germination rate, cell number and the effect of metabolic products. The results showed that addition of 6218u protein hydrolysates may simultaneously improve the Saccharomyces cerevisiae growth, the conversion ratio of reducing sugar and ethanol content significantly.
