摘要
在２０～４０℃条件下对管囊酵母进行了培养，研究其生物量、乙醇产量、残糖量等指标随温度变化的消长趋势，以及在不同温度下在对数生长期各项动力学参数的变化。该菌株的最适培养温度为２８～３２℃，在这一范围内，比生长速率、比乙醇产率和木糖比消耗速率分别达到最高值：０．１９／ｈ、４．３ｇ／（ｇ·ｈ）和２８．０ｇ／（ｇ·ｈ）。
The influence of culture temperature on growth of pachysolen tannophillus is remarkable. In this paper, the biomass, ethanol yield and residnal sugar in culture broth of this strain at 20￣40 ℃ had been studied. At different temperature, the kinetic parameters during exponential phase were given. The optimal temperature is from 28 ℃ to 32 ℃. At this range, the specific ethanol production rate and specific xylose consuming rate were better.
