ABSTRACT:
A method of removing pollutants from porous, solid materials uses a biomass loaded onto a support. The biomass is put into contact with a pollutant contaminated porous, solid material so that the bacterial biomass degrades the pollutant. The moisture level of the support and biomass are maintained at a level that optimizes pollutant removal and is a function of the relative solubility of the pollutant.
