You have a tube of nutrient broth, in which E. coli is growing. Upon analyzing the broth chemistry, you find:___________
1) oxygen content has dropped a bit, but carbon dioxide has gone up a lot,
2) formic, acetic, and lactic acids are present.
What kind of metabolism has most likely occurred?

Answer:

The metabolism that most likely occured was a mixed acid fermentation.

Explanation:

The metabolism of E. Coli is heterotroph, facultative anaerboic. This means that the organism can generate energy by using oxygen but also by mixed acid fermentation. As the analysis of the broth showed the presence of formic, acetic and lactic acids and increased levels of carbon dioxide - all products of the mixed acid fermentation - we can suppose that the mixed acid fermentation occured.

in this question, we will answer questions about E.coli and its metabolism.

E.coli and its metabolism

  1. You have a tube of nutrient broth, in which E. coli is growing. When analyzing the chemistry of the broth, you find: phosphorylated and/or carboxylic acids and coenzyme thiol esters
  2. The oxygen content has dropped a little, but the carbon dioxide has risen a lot. In the absence of oxygen, glucose fermentation or fermentative growth occurs with production essentially of ethanol, acetate, formate, succinate and lactate
  3. Formic, acetic and lactic acids are present. What kind of metabolism likely took place? Fermentative

With this information, we can conclude that E. coli is a facultative anaerobic bacterium.
