If you use glucose broth medium without a pH indicator how can you determine whether a particular bacterium fermented glucose?

Answer 1

you can use a durham tube and observe the formation of a bubble for the microbes that are expected to produce gas

Answer 2

You can determine whether a bacterium fermented glucose by performing a series of biochemical tests. Some common tests include measuring gas production, pH changes, and presence of fermentation products like acids or alcohols. Additionally, you can use specific reagents or methods tailored for detecting fermentation byproducts to confirm the presence of fermentation.
