✦ Synopsis
Effect of initial sucrose concentration on the production of j3-fructofuranosidase from Aspergillus japonicus TIT-90076 were investigated in shaking batch cultures. The maximal enzyme production occurred at 2.5 % (w/v) sucrose and an inhibitory effect on cell growth was exhibited when the initial sucrose concentration was above 10 % (w/v). For evaluation of the process economy, a relationship between the process output (FFase production at 96-h cultivation, in units ml') and the process input (initial sucrose concentration, S,, in % (w/v)) can be simply expressed as follows: FFase production = (142.98J29.3 + S,))(16.7 -0.22SJ.
