5-11 Decarboxylation test
1. Write the molecular structure of the carboxyl group.
2. What promotes the production of the decarboxylase enzyme in decarboxylase-
positive microorganisms?
3. What process causes the decrease of pH in the medium in the decarboxylation test?
4. What is the purpose of the addition of the mineral oil layer after inoculation in the
decarboxylation test?
5. Why does the decarboxylase-positive tube turn yellow before it turns purple?
6. This decarboxylation test cannot be performed successfully on organisms that cannot
ferment glucose. Explain why.
7. What amino acid is being decarboxylated in this test?
RESULTS / INTERPRETATION
Draw out your results. Be sure to properly label the test tubes with the organism, color
results,
and describe if the results were positive or negative and interpret the results.
