A yeast autolysate or yeast autolysate extract is made by fermentation of yeast to a concentration level where the yeast dies and the cells walls break. The proteases from the yeast itself start the digestion of the proteins and split them into peptides and amino acids. The insoluble portion is removed.
The yeast inthis flask will use up the oxygen inside the flask and willferment glucose to produce carbon dioxide. The CO 2 will displacethe remaining air, which will bubble out through the water. Thisflask will not contain oxygen after the first hour or two of theexperiment.EACHER REFERENCE PAGES-YEAST FERMENTATION LAB.

Place 50 mL of Bromothymol blue solution into a 125 mLErlenmeyer flask.2.
