【摘要】 在甘油发酵初期 ,采用 30℃的温度促进细胞生长 ;随后采用 40℃的温度促进甘油的产出。与传统的 35℃恒温发酵相比 ,在摇瓶及 15L气升式反应器中采用变温发酵 ,最终甘油的产率分别提高 2 8.7% ,34.0 %。更多还原

【Abstract】 General temperature scheme in glycerol production by fermentation should start at 30℃ in a short former stage to improve cell growth rate, then be maintained at 40℃ in the following stage to improve glycerol production. In experiments using 1000ml shaking flask and 15L ALR, the final glycerol yield with temperature variation were enhanced respectively by 28.7% and 34.0% as compared with that at conventional 35℃.更多还原
