| 摘 要： | 从本地白酒酒曲中成功分离出9株酵母菌,依次命名为Y-1～Y-9。比较了这9个菌株的生理生化特性、耐高温能力和耐酒精能力等特性。结果表明:分离的9株酵母菌上述特性差别较大,其中,Y-4各方面均表现突出,该菌株能利用木糖在内的多种糖源,在45℃下生长良好,能耐14%的酒精度。对橘子汁为原料进行的发酵实验表明,上述菌株均能以橘子汁为原料生产酒精,其中,Y-4发酵能力最强,发酵84h后,CO2失重为12.913g。综上所述,Y-4是一株极具潜力的燃料乙醇生产工程菌株。

| Abstract: | Nine yeast strains were isolated from local wine yeast,and named as Y-1 to Y-9. Their physiological and biochemical characteristics,high-temperature endurance and high-alcoholicity endurance were compared. The results showed that remarkable differences were observed among the nine yeast strains. Among of them,Y-4 was suggested to be the optimal strain,based on the fact that it had a good utilization of sugar,that it could assimilate multiple sugar sources including xylose. In addition,Y-4 was capable of gro... |
