The scale-up of inulinase production in aerated cultures of Candida kefyr DSM 70106 was studied, taking into account the criterion of maintaining K L a constant. The culture was carried out batchwise, in a 15-L fermentor, with K L a varying from 25 to 199 h-1. The highest inulinase production was attained with an initial K L a value of 46 h-1. A large scale fermentation (300-L fermentor) was performed using identical culture medium conditions. The responses obtained for the bench and scaled-up experiments showed similar behaviors, and the results were, respectively, 0.60 and 0.58 U•mL-1•h-1 for productivity and 43.0 and 41.5 U•mL-1 for activities.
