Rapid Assessment of Yeast Viability and Yeast Vitality During Alcoholic Fermentation
Open accessAbstract
A flow cytometric method based on the measurement of the efflux percentage of carboxyfluorescein after staining of yeast cells with carboxyfluorescein diacetate is reported. This efflux percentage was followed throughout alcoholic fermentations performed with various pH and temperature conditions. The results obtained show that the efflux percentage is a good indicator of the energetic state of yeast cells and varies through the fermentation in a similar manner to the specific ethanol production rate. These results suggest that this flow cytometric method can be applied to assess viability and to predict vitality of yeast cells in alcoholic fermentations.

In the citing paper
“Beer quality is greatly influenced by the biochemical performance of the yeast and therefore it is important for brewer's to be able to accurately predict yeast viability (also known as yeast vitality). In order to optimize fermentations, it is vital to determine yeast viability in order to adjust the pitching rate accordingly [16].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
