Abstract
During continuous alcoholic fermentation, Saccharomyces cerevisiae 38A floc concentration was monitored using an on-line impedance probe. Since the se nsor response is linear and does not depend significantly on yeast particle size, an automatic technique of determining the yeast growth rate has been developed and validated against the conventional mass balance method.
