Enumeration of Bacteria in Suspensions Using Time Domain Reflectometry.

ABSTRACT: Microbial detection techniques, such as bacterial counting, are essential in all aspects of environmental monitoring and analysis. However, the standard plate count method for bacterial enumeration with colony-forming units is time-consuming and labor-intensive. In this study, we present a fast and accurate method to count bacteria cells using the technique of time-domain reflectometry (TDR) based on the electrical properties of bacterial cell suspensions. A series of suspensions with various bacterial concentrations were used as the test materials, and the electrical conductivity (σ_a) was determined using the TDR method. The TDR measured-σ_a value was converted to the concentration of bacterial suspension using a pre-established standard curve on three types of bacter
