The decarboxylase tests determine
A) whether the bacteria possess enzymes capable of removing the carboxyl group of specific amino acids in the test medium.
B) whether the bacteria can further metabolize the acids formed during fermentation to 2,3 butanediol.
C) if bacteria can maintain an acid pH if only sucrose is present in the media.
D) to see if $\alpha$-naphthol can be broken down into its constituent parts: acetoin and diacetyl KOH.

Question

Quizplus · Accepted Answer

The decarboxylase tests are used to determine if bacteria have enzymes that can remove the carboxyl group from specific amino acids in the test medium. This is important because some bacteria use decarboxylation as a means of producing energy or as a way to regulate pH in their environment. By testing for the presence of decarboxylase enzymes, we can gain insight into the metabolic capabilities of different bacterial species. Options B, C, and D are not accurately describing the purpose of decarboxylase tests.
