The results of the study provided early evidence for the role of the stomach in hunger regulation and helped establish a foundation for modern research on appetite control. [1] The experiment was groundbreaking in its approach, combining objective physiological measurements with subjective experience reports, and marked a significant step ...
The effect was described by Louis Pasteur in 1857 in experiments showing that aeration of yeasted broth causes cell growth to increase while the fermentation rate decreases, based on lowered ethanol production. [4] [5]
YEPD or yeast extract peptone dextrose, also often abbreviated as YPD, is a complete medium for yeast growth. It contains yeast extract, peptone, double-distilled water, and glucose (dextrose). [1] It can be used as solid medium by including agar. The yeast extract will typically contain all the amino acids necessary for growth.
Elephant's toothpaste is a foamy substance caused by the quick decomposition of hydrogen peroxide (H 2 O 2) using potassium iodide (KI) or yeast and warm water as a catalyst. [1] How rapidly the reaction proceeds will depend on the concentration of hydrogen peroxide.

Lab notebook with the complete record of the experiments underlying a published paper. [1] Chemistry stencils that used to be used for drawing equipment in lab notebooks. A laboratory notebook ( colloq. lab notebook or lab book ) is a primary record of research .
More than one stub template may be used, if necessary, though no more than four should be used on any article. Place a stub template at the very end of the article, after the "External links" section, any navigation templates, and the category tags. As usual, templates are added by including their name inside double braces, e.g. {{Yeast-stub}}.
Analysis of native aqueous samples, concentrated environmental samples and chemicals or mixtures in solvents like ethanol or DMSO is possible. Results can be obtained as quickly as after an overnight exposure. [4] The handling of yeast cells is generally less demanding than mammalian cell culture.
