Dielectric Behavior of Staphylococcus Aureijs in Viscous Media

Abstract

The radiofrequency dielectric behavior of suspensions of Staphylococcus aureus bacterial cells in mixtures of water, sucrose and glycerol has been investigated. Dielectric measurements ere made in bacterial suspensions of about 1.0 × 10¹⁰ cells/1 at 27 ± 0.5°C in the range from 0.1 to 100 MHt. The relative permittivity dispersion curves exhibited a shift towards the high frequencies as the viscosity of the suspending medium was decreased. The dielectric dispersion parameters have been presented on the basis of the curve-fitting analysis used.
