A MAGNETIC METHOD FOR DETERMINING VOLUME FRACTION IN YEAST SUSPENSION

Abstract

1) On the basis of the additivity of magnetic susceptibility, a new method was presented for estimating the volume fraction of microbial cells in suspension.
2) Yeast cells were used for making a comparison between the magnetic volume fraction thus obtained and the morphological volume fraction.
3) The present method gives an estimate of the cell space surrounded by the cell membrane, thus making a basis for dielectric studies of cell suspensions.
