Using a specially designed miniature probe mounted into a plate across which water contaminated with the bacterium Pseudomonas fluorescens was flowing, oxygen levels at the biofilm/substrate interface have been determined. The experimental results show a rapid fall in the amount of oxygen available to the micro‐organisms in the layers near the interface. As the biofilm approached 300 μm in thickness higher flow velocities across the biofilm had little effect on oxygen availability in the regions near the interface.
