[Studies on optimal conditions for inulinase production by Kluyveromyces sp. Y-85]

The application of response surface method to optimal medium-screeing for inulinase production by Kluyveromyces sp. Y-85 has been investigated. The experiments of condition control for the enzyme production was carried out in a 15 L fermenter. A large scale fermentation (1000 L fermenter) was performed five batches, and average inulinase activity of 68.9 u/ml achieved.
