  abstract = {{F}ungal biofilters attain higher toluene elimination. rates compared to bacterial systems. {H}owever, strong mycelia growth can cause clogging. {I}n the present work, toluene biofiltration with the fungus {P}aecilomyces variotii {CBS} 115145 was tested with two rigid packing materials that allow high mycelia growth. {T}he reactor had two 4.25 {L} sections, each packed with ceramic {R}aschig rings differing in water retention capacity and internal porosity. {A}fter optimizing nutrient solution delivery, an overall maximum elimination capacity of 245 g/m(3)/h was obtained. {H}igher elimination capacity (290 g/m(3)/h) was measured in the ceramic ring with lower water content, indicating the interest of such packing material for treating hydrophobic pollutants in fungal biofilters. {A}dditional experiments with this support in a 2 {L} biofilter showed bacterial contamination, but the fungal activity was responsible for about 70% of the total removal. {T}he support with less humidity showed greater aerial growth, which possibly improves removal efficiency by favoring the direct transfer of pollutants from the gas phase to the microorganism.},
