Abstract
In this paper a model is presented which can be used to simulate the behaviour of xenobiotic chemicals in soil columns with respect to their physical and chemical properties. Terms describing biological transformation of xenobiotics are also included in the model. It incorporates microbial growth following Monod kinetics and a chemotactic response of the transforming bacteria towards the xenobiotic substrate. The model appeared to yield good simulations of an experiment by Van der Meer et al. (1987) who investigated the degradation of 1,2-dichlorobenzene in soil columns inoculated with
Pseudomonas sp. strain P51. The behaviour and the fate of 1,4-dichlorobenzene as found by Kuhn et al. (1985) can also be simulated using this model but their results were also adequately simulated using a simple second order model. The results generated by the model correspond to kinetic parameters obtained in other studies. It is concluded that the model is a useful tool for the investigation of the activity of bacteria degrading xenobiotics in soil columns, provided that the microbial parameters can be determined in independent experiments, and that the active microbial mass in the soil can be measured.
