To reduce the threat and increase usefulness of microorganisms, it is necessary to have a better understanding of their biological functions. It is important to evaluate the bacterial activity in real time for various purposes such as hygiene management, development of antibacterial agents, and effective utilization of bacterial resources. This requires a quantitative assessment of metabolic processes such as growth and respiration. Here, we would like to introduce the development of electrochemical methods for assessing bacterial activity.
