[Immobilization of Saccharomyces yeast cells on electret polyethylene films].
The method of electret-thermal analysis developed in dielectric physics has been applied to monitor bioelectric phenomena that accompany the immobilization of microorganisms on electret substrates. A spectrum of thermo stimulated currents for biofilms consisting of immobilized Saccharomyces cells has been obtained. The spectrum represents a halo in the region of 30-90 degrees C. The immobilization of Saccharomyces cells on electret polyethylene films results in their depolarization that is recorded on the spectra of thermostimulated currents as a reduction of the current peak corresponding to the polyethylene melting point. A hypothesis has been put forward that explains the phenomenon by the absorption of the electric energy of polarized substrates by the cells for the occurrence of metabolic reactions.
