Abstract :
The growth modelling of the bacterium Photorhabdus luminescens is proposed. Cultivation in liquid culture of the bacterium used in biological pest control is strongly influenced by the control inputs pH value and substrate concentration. Two modelling strategies-formal kinetic approach and model based gas analysis-are presented to mathematically describe the bacterial growth as a function of the substrate concentration. The biomass concentration and the substrate consumption can be estimated by using a combination of these approaches
