Abstract
A comparison of β-fructofuranosidase (FFase, EC 3.2.l.26) production by Aspergillus japonicus TIT-90076 in batch and fed-batch cultures was investigated in shaken flasks. Results showed that fed-batch cultivation of A. japonicus using intermittent sucrose supply produced more FFase than batch culture, and the maximal enzyme production was 910 units ml−1, which was about 20% higher than that in the batch cultures.
