A bacterial culture grown in a glucose- peptide medium causes the pH to increase. The bacteria are most likely

Question

Quizplus · Accepted Answer

When bacteria use peptides (proteins) for energy, they often release ammonia (NH3) as a byproduct, which increases the pH of the medium. This is because the deamination of amino acids (the process of removing an amino group from an amino acid) results in the production of ammonia, which is a basic compound. Fermentation of glucose (A) typically produces acidic byproducts, lowering the pH. Oxidizing glucose (C) for energy would not directly cause an increase in pH. If the bacteria were not growing (D), there would be no significant change in the pH due to bacterial activity.
