Summary
A series of packing materials, non porous and porous, were tested, in order to elucidate the most important factors for colonization. It seemed that respectively surface roughness and total porosity plus pore size are mostly affecting the colonization velocity. Reticulated polyurethane foam appeared an excellent colonization matrix.
