Background

The impedance method is a rapid detection method for determining the content of microorganisms in a sample by measuring the change of the electrical characteristics of a culture medium caused by the metabolism of the microorganisms. During the culture process, the metabolism of the microorganisms can metabolize the electrically inert macromolecular substrates in the culture medium, such as carbohydrates, proteins, fats and other nutrients, into electrically active small molecular products, such as amino acids, lactate, acetate and the like. As the microorganisms grow and multiply, the electrically inert molecules in the medium are gradually replaced by the electrically active substances, so that the electrical conductivity of the medium increases and the electrical impedance decreases. The initial number of microorganisms varied, as did the time to exponential phase increase.
