【摘要】 研究了20余种工业化葡萄酒活性干酵母对高温与低温的适应性。结果表明,供试菌株在37℃均生长良好,其中10#-1,10#-2,11#-1,11#-2和21#等5个菌种在供试菌中较耐高温,在45℃仍可生长;在10~16℃培养时,随着温度的降低,菌体生长的速度减慢,其中9#,15#,18#,26#,27#和30#对低温(10℃)的适应性略强;同一菌种个体间在生长速度和生长量上存在差异。

【Abstract】 More than 20 kinds of dry wine yeasts were used for the characteristic study of high and low temperature tolerance in this paper.The results indicated that all the yeasts could grow at 37 ℃.Less yeasts could grow with the temperature increasing.Five yeast strains (10~#-1,10~#-2,11~#-1,11~#-2,21~#) have the ability growing in high temperature (45 ℃).And when the temperature was much low ((10-16 ℃)),the growth rates were slowed down with the temperature decreasing.Six strains (9~#,15~#,18~#,26~#,27~# and 30~#) grew better in low temperature.Differences could be observed in different growth conditions,as well as in growth rate and in growth capacity.
