Abstract

The kinetics models for lipase batch fermentation by Bacillus cereus CGMCC No.12336
were studied.During the fermentation process of B.cereus CGMCC No.12336,cell density,
lipase activity and reducing sugar content were determined,respectively.Based on the Logistic
and Luedeking-Piret equation,the kinetics models of cell growth,lipase formation and substrate
consumption were established by nonlinear least-squares fitting method and the kinetic parameters
were obtained.The verification of the experimental results demonstrated the accuracy of the
model and indicated that the kinetics models were in good agreement with the experimental data,
which was used for the description of the fermentation process.
