"EXPERIMENTAL STUDIES ON SEDIMENTATION OF YEAST CELLS"

Abstract

Hindered settling velocity of yeast cells, Saccharomyces cerevisiae suspended in a buffer solution was measured. So far as the experimental range used in the present study was concerned, the results obtained were substantially identical with those reported for other suspensions.
It was shown that the shape of particles, irrespective of whether they are "isolated" or "flocculated", could be correlated in quantitative terms to the relative velocity of hindered settling which is controlled by the viscous force of liquid.
In connection with this, further studies on the shape of flocs and the degree of flocculation, an evaluation of which is frequently required in handling microbial suspensions, seem to be fruitful.
