摘要
从酒药中分离得1株能产真菌丝的酵母,定名为DS56,对其发酵力、耐酒精度、生长状况进行了测定。结果表明,发酵结束产酒精1.5%(v/v),耐酒精度达13%(v/v),是一株糖化力较强的酵母,在生米粉中生长繁殖快;在饭上生长稍慢;在麦芽汁琼脂培养基表面生长快,形态多样;在液体里生长缓慢。产酒精能力弱,产酯能力强。在黄酒酿造中可用于制作酒药,使酒药产生特有香气,但在发酵过程中作用不大。(庞晓)
The yeast,which could produce fungi hypha named DS56,was separated from wine yeast and its fermentation capability,alcohol resistance capability and growth conditions were determined.The results indicated that after fermentation1.5%(v /v)alcohol pro-duced and the alcohol resistance capability achieved13%(v /v).And the yeast had the characteristics:strong saccharifying power,rapid propagation and growth in uncooked rice noodle and slight slow growth in rice,rapid growth in various forms on the surface of wort agar culture medium,and slow growth in liquid.The strain had strong ester-producing capability and weak alcohol-producing ca-pability.It could be used in yeast production and produce specific aroma in yeast but had slight functions in the fermentation.(Tran.by YUE Yang)
