Question

Assume you are working for a chemical company and are responsible for growing a yeast culture that produces ethanol. The yeasts are growing well on the maltose medium but are not producing alcohol. What is the most likely explanation?a. the maltose is toxic
b. O₂ is in the medium
c. not enough protein is provided
d. the temperature is too low
e. the temperature is too high

Answer 1

Answer:

D - The temperature is too low

Explanation:

The fermentation process has limits such as temperature. Greater than 27°C kills the yeast less and than 15°C results in yeast activity which is too slow.

Therefore, if the yeasts are growing well on the maltose medium but are not producing alcohol it is as a result of low temperature
