pH及通气量对法夫酵母生物量以及所产6G-果糖基转移酶活性的影响
Effect of pH and ventilatory capacity control strategies on biomass and 6G-fructofuranosidse activity of Xanthophyllomyces dendrorhous in the fermentor
摘要
Abstract
The effect of inital culture pH and controlled pH ranging from 7.0 to 9.0 and VC(ventilatory capacity)ranging from 5 to 12L/min on biomass and 6G-lructofuranosidase activity by Xanthophyllomyces dendrorhous which were using in the free-whole-cell biotransformation were investigated in batch fermentation.An optimal pH of 7.0 and VC of 5L/min were obtained for cell growth,cell density was/11.6g/L and 11.8g/L,respcctively,and an optimal pH of 8.0 and VC of 8L/min were obtained for 6G-fructofuranosidase activity,both of them were 0.32mol/L/min Comprehensive consideration of the cell density and 6G-fructofuranosidase activity,the final optimal pH and VC for fermentation was 8.0and 8L/min,respectively.关键词
