Exhaust gas monitoring of fermentation processes

fermentation, as fermentation activity is reflected in the consumption of O 2 and the production of CO 2. Any deviation from the optimal metabolism of the microorganism will be reflected in the ratio between production of carbon dioxide and consumption of oxygen the socalled respiratory quotient (RQ).

Fermentation with yeastLabQuest

Yeast are able to metabolize some foods, but not others. In order for an organism to make use of a potential source of food, it must be capable of transporting the food into its cells. It must also have the proper enzymes capable of breaking the food’s chemical bonds in a useful way. Sugars are vital to all living organisms. Yeast are capable of using some, but not all sugars as a food …
