ResumoExperiments were carried out to study the effect of flow shear stress on the rate of accumulation of bottom-attached biofilms. Natural harbour water without special nutrient enrichment was circulated through an outdoor open channel, simulating natural river conditions. Biofilm development on small glass plates (15 × 25 mm) placed on the bottom of the channel was monitored through microscopic examination and determination of total carbohydrate by a recently developed biochemical method. Results indicate that biofilm biomass accumulation was substantially reduced as flow shear stress increased and that the maximum accumulation occurred under very low flow conditions.
