WebApr 11, 2024 · Yeasts have been a part of human life since ancient times in the fermentation of many natural products used for food. In addition, in the 20th century, they became powerful tools to elucidate the functions of eukaryotic cells as soon as the techniques of molecular biology developed. Our molecular understandings of metabolism, cellular … WebStaining is done to test whether yeast are viable or not (living or dead). A toxic staining agent, frequently methylene violet or methylene blue, is mixed with a yeast sample where it is quickly absorbed. Living cells will force the staining agent out of the cell while the dead cells will not, and as such, will appear stained under a microscope 3.
