Monitoring the growth and stress responses of yeast cells by two-dimensional fluorescence spectroscopy: First results

Podrazký, O., Kuncová, G., Krasowska, A., Sigler, K.·2003·Folia Microbiologica

Abstract

S. cerevisiae growth and responses to different treatments were monitored by two-dimensional fluorescence spectroscopy, which simultaneously detects the fluorescence of a number of cells' own fluorophores. Growth curves of cultures of free cells were measured by means of tryptophan fluorescence in nonfluorescent culture medium and a flow-through system at a suitable excitation/emission beam geometry. Fast responses of the cells to anaerobic-aerobic transition or addition of glucose, methanol or cyanide, which could not be measured in this system because of the time delay inherent in transporting the cells from the culture flask to the cuvette, were monitored with cells immobilized in alginate. The major fluorescence changes caused by these treatments belonged to NAD(P)H which is a good indicator of the redox state of the cells.

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.
