Fed Batch Fermentation

The effects of sucrose concentration, pH, temperature and aeration rate on the production of biomass and inulinase (2,1-beta-D-fructan fructanohydrolase, EC 3.2.1.7) were investigated using fed-batch fermentation by Kluyveromyces marxianus var. bulgaricus. The best sucrose concentration for enzyme activity was 10 g L-1, whereas activity was inhibited when the sucrose concentration was 20 g L-1. Enzyme activity was strongly influenced by pH of the culture. pH 5.0 was the most suitable for both enzyme activity and cell growth, achieving 98.04 U mL-1 and 14.05 g L-1, respectively, after 72 hours of cultivation. The highest production of inulinase and biomass was observed at temperatures of 25oC and 30oC, whereas a decrease in activity was observed at 35oC and 40oC. The best aeration rate was 1.0 vvm. The increase in aeration rate or oxygen injection provided no increase in enzyme activity and biomass.
