Answer
The steps for conducting a fermentation test include preparing the fermentation medium, inoculating with the microorganism, incubating under anaerobic conditions, and observing for gas production or pH changes.
Solution
a
Preparation of the fermentation medium: The medium should contain the necessary nutrients and indicators for the desired fermentation process
b
Inoculation of the medium with the microorganism: Introduce the microorganism into the medium under sterile conditions to prevent contamination
c
Incubation under anaerobic conditions: Place the inoculated medium in an anaerobic environment, typically at a temperature suitable for the microorganism's growth
d
Observation and interpretation of results: After incubation, check for gas production, pH changes, or other indicators of fermentation
Key Concept
