Description	The response of biofilters to varying periods of starvation and to changes in inlet con-centrations of a mixture of toluene and xylene have been tested in laboratory-scale biofilters packed with a mixture of Perlite and compost. These results have been mathematica1ly mode1led taking the emission of carbon dioxide as a proxy for kinetics measurements. The use of CO2 is a more practicalapproach than that of kinetics based upon batch experiments on pure cultures. A simplification of Zarook's method, our model produced good outlet predictions given sma1l changes in the inlet concentration oftoluene and xylene. But for more stressful situations, like the resumption ofthe feed after periods ofstarvation, the use of carbon dioxide proved to be inappropriate as an indicator ofthebiomass activity, greatly overestimating biofilter performance. This suggested either the occurrence of cryptic growth (as a result of the stress inflicted on the biomass) or perhaps the utilisation of thecompost as a carbon source.
