Measure in biofilm or cultures of bacteria
In microbiology, microsensors can be used to measure concentrations and concentration gradients in pure cultures of bacteria, cyanobacteria, and algae. Also microbial biofilms can be studied in detail. A few examples are listed below.
Light induced microbial respiration
A Unisense oxygen microsensor was inserted into a pure culture colony of Rhodospirillum centenum, and respiration rates were determined by measuring changes in oxygen concentration. With this procedure it was possible to evaluate the influence of light on respiration rate.
Microbiology of the mouth
Unisense oxygen microsensors can be used to study bacterial respiration in dental plaque during scientific experiments. Bacterial assemblages on teeth are known to develop caries through the acidification of the environment as a result of respiration. It can be of interest to study the respiratory activity of these microbial assemblages in order to evaluate the efficiency of anti-caries treatment on teeth.
