Secondary utilization of trace organics by biofilms on porous media

Laboratory experiments with fixed-bed biofilm reactors demonstrated that compounds representative of common classes of organics could readily be biodegraded at concentrations well below phase necessary to support the biofilm at steady state Des composes representatifs des classes communes de composes organiques (acetate, galactose, alanine, thymine et phenol) peuvent etre biodegrades dans un reacteur, a lit fixe a des concentrations tres inferieures a celles necessaires a maintenir le biofilm en regime permanent
