STUDY ON INTRACIRCULATED AIR-LIFT FERMENTOR

Fang Fengshan Li Xiangpeng Hu Likan Chen Wenying Wang Dachen (Shanghai Institute of Organic Chemistry, Academia Sinica, Shanghai)  
A 55 1 intracirculated air-lift fermentor has been developed, in order to meet the requirement of equipment for yeast industry especially for the hydrocarbon yeast.In this study, the relationship between the major parts of fermentor, such as the diameter of the draft tubes, different kind of air-spargers, the screen plate fixed inside the draft tube etc., and its properties have been examined by both the oxygen transfer rate and fermentation of n-paraffins.Furthermore, it has been found that the oxygen transfer rate ( N_a ) was the function of the volume ratio of air to liquid (Q/V) multiplied by the height of fermentation media (H), as given by the following equation;N_2=0.51·Q/V·(H)~(0.75)Under the experimental conditions, the oxygen transfer rate reached 210 mmole O_2/1·h. Also by using C_(14)—C_(18) n-paraffins as sole carbon source for continuous cultivation of Candida tropicalis Y-17, the emulsification of the oil and water in the fermented broth was satisfactory, and the productivity rise 2.7g/1·h.This fermenter has been scaledup to 1000 1, 6000 1 and 12 m~3 successfully
