Abstract

Ground glass and roughened polystyrene model stream beds supported mixed microbial biofilms capable of removing Cu , Cd and Pb from running waste waters. Metal uptake by these biofilms was compared to that of similar free-living, mixed microbial populations exposed to different metal concentrations and combinations. Metal uptake by the biofilms was on average 17 times better than that by the free-living cultures.
