United States Patent Application

Systems and methods of monitoring microbial growth rates are provided. In particular, a sensing electrode having a working electrode and a counter electrode can be positioned in a microbial environment. An alternating current signal can be applied to the working electrode. The signal can then propagate through the microbial environment and can be measured at the counter electrode. The presence of microorganisms in the microbial environment can cause changes in the signal as it propagates through the microbial environment. Such changes in the signal can be used to determine one or more signal parameters associated with the microbial environment. The one or more signal parameters can be used to determine a microbial growth rate. Nutrient concentrations can then be adjusted in the microbial environment to facilitate an optimal growth rate.
