Abstract: Burkholderia pyrrocinia JK-SH007 isolated from poplar can inhibit the pathogenic fungi in poplar. To optimum fermentation process of strain JK-SH007, fermentation kinetics were investigated in this study. A kinetic model for the simulation of bacterial growth, the inhibition of fungal activity generation and glucose consumption were constructed by using Logistic equation, Luedeking-Piret equation and Luedeking-Piret like equation, respectively, based on the data from fermentation experiment. The calculated values in kinetic models fit well with experimental values which directly reflected the kinetic characteristics during the batch fermentation process of strain JK-SH007. Moreover, the fermentation kinetics model provided a foundation for the optimization and amplification of fermentation process.
