【摘要】 培养温度对运动发酵单胞菌有很大的影响。本文研究了在20℃～40℃范围内培养运动发酵单胞菌时,其生物量、乙醇产量、残糖量等指标的变化情况,并研究了在不同温度下在对数生长期间各项动力学参数的变化。运动发酵单胞菌的最适培养温皮为30℃～33℃,在这一范围内,比乙醇产率、比生长速率、葡萄糖比消耗速率等各项指标都较好。更多还原

【Abstract】 The influence of culture temperature on growth of Zymomonas mobilis is remarkable. In this papers, the biomass, ethanol yield and residual sugar in culture broth of Z. mobilis at 20℃-40℃ had been studied. At different temperature, the kitneic parameters during exponential phase were given. The optimal temperature for Z .mobilis is from 30℃ to 33℃. At this temperature range, the specific ethanol production rate and specific glucose consuming rate were better.更多还原
