Original Paper


Lipid phosphate, which is a measure of viable biomass, was determined using biofilm samples from three different laboratory-scale reactors. The analysis procedure proposed in the literature was modified and tested for suitability in experiments with biofilm reactors. The microbial contents of the biofilms studied are compared in three types of reactor.
