– O2, H2S and pH microprofiles in biofilm. Microbial mats undergo daily cycles that are characterized by dramatic changes in oxygen, pH and H2S dynamics. The mats are highly active systems with functional layers of only a few hundred microns. To investigate the dynamics within these layers it is important that measurements in the mat […]

The respiration of a cell culture combined with the low diffusion rate of oxygen in the growth medium can lead to a marked decrease in oxygen tension close to the cells. Depending on the particular circumstances, this phenomenon may interfere with other factors that one attempts to study and complicate interpretation of the results. Unisense […]
