Primary Study on Kinetics Model of Bacillus subtilis Batch Fermentation

Abstract

Abstract: The fermentation process of Bacillus subtilis,an antagonist for postharvest biological control of green mold and blue mold on citrus fruit,was studied in a 70-L batch system.A simple model was proposed with the Logistic equation for growth, the Luedeking-Piret equation for antifungal substance production and Luedeking-Piret-like equation for substrate consumption, respectively.The fit values of the three models are 0.9934,0.8312 and 0.9455,respectively.The model appeares to provide a reasonable description for each parameter during the growth phase.
