摘　　要：以玉米粉-麸皮糖化液和葡萄糖-土豆汁为2种不同发酵主料,对益生菌产阮假丝酵母菌MYS-J1在70L全自动发酵罐条件下的发酵规律进行了深入研究,结果表明:在70L全自动发酵罐中装填系数为60%,温度30℃,接种量3%,通气量为1.5m3/h,罐压0.04MPa的条件下,酵母菌在玉米粉-麸皮糖化液下发酵时,最佳发酵水平可达6.46×108cfu/mL;酵母菌在葡萄糖-土豆汁中发酵时,最高发酵水平可达4.55×108cfu/mL。另外,总结了产阮假丝酵母菌MYS-J1在发酵罐中的生长曲线以及发酵过程中pH值、含糖量、生物量、固形物含量的变化趋势。The fermentation ofprobiotic Candida utilis MYS-J1 in 70 L automatic fermentor were investigated in cornmeal-bran syrup or glucose-murphy juice medium. It was shown that the highest fermentation level of C. utilis MYS-J1 was 6.46×10^8 cfu/ml and 4.55×10^8 cfu/ml in cornmeal-bran syrup medium and glucose-murphy juice medium, respectively, when the medium volume was 60% of fermentor, inoculum was 3%, and the fermentation was conducted at 30℃ with ventilation volume of 1.5 m^3/h and fermentor presser of 0.04 MPa. In addition, the growth curve of C. utilis MYS-J1 and the variation ofpH, sugar content, biomass and solid content during fermentation were also summarized.
