Dead boiled yeast suspension?
A dead boiled yeast suspension is a mixture containing yeast cells that have been heat-treated to kill them. This type of suspension is commonly used in laboratory settings for research purposes as a source of cell components or as a control for experiments involving live yeast. It is important to note that dead yeast cells can still provide valuable information in certain experimental setups.
What is the difference between boiled and unboiled yeast?
Boiled yeast has been heated to a high temperature, which kills the yeast cells and deactivates the enzymes. Unboiled yeast is live and active, capable of fermenting sugars and producing carbon dioxide. Boiled yeast is typically used in recipes that do not require fermentation, such as bread recipes that call for instant yeast.
