bio 250 L week 8 laboratory questions
and detailed correct answers passed
with first time trial
a biooxidative process, not requiring 02 (but can be completed in the presence of O2 as well), in
which an organic substrate (like Glucose) serves as the final electron accepter and produces an
organic acid - answer ✔✔-fermentation
inverted glass tube inside test tube; will collect any CO2 gas if produced during fermentation -
answer ✔✔-durham tube
Indole
Methyl Red
Voges-Proskauer
Citrate - answer ✔✔-IMViC test components
Test unknown's ability to degrade Tryptophan via the enzyme tryptophanase, So we are
detecting an end product (indole) from the reaction of an enzyme (tryptophanase) - answer
✔✔-Indole test
positive result, indole is present which means that the organism has the enzyme tryptophanase
and is able to degrade tryptophanase - answer ✔✔-positive indole result
