Ultra Low Frequency Yeast Cells Electric Activity

Abstract

This paper presents results from the measurement of the electrical activity cold sensitive beta-tubulin mutant tub2-401 of yeast cells in frequency region 0.4 - 1.6 kHz. 25 measurements of both synchronized and nonsynchronized cells show that the synchronized cells have higher electrical activity which corresponds to the findings of Pohl et al. Local nanomechanical vibrations of yeast cell membrane have been measured by Pelling et al. with Atomic Force Microscopy in same frequency region. Mechanical oscillations of electrically polar structures in cell may give rise to electric oscillations we measured.
