Question

Did the unknown bacteria show any difference in results for the three sugars tested? If so, explain the differences in the sugars used. If not, explain how the sugars are similar in structure.

Explanation / Answer

Yes the unknown bacteria shows difference in result for the three sugars tested.

Glucose fermentation is a biological technique utilized in the microbiology to determine the way microorganism metabolises glucose.

Microorganisms can metabolise some sugars but not others that is chemical break down of the sugar by microorganism.

So this unknown microorganism ferments or utilizes lactose sugar but cannot ferment fructose.

Now let's discuss the similarities & difference of these sugars.

Glucose is a simple sugar & is a monosaccharide meaning it is made of only one sugar.

Lactose is a disaccharide sugar that is , it is made of 2 sugars namely glucose & galactose.

Fructose is also monosaccharide like glucose which is made up of single sugar molecule.

Based on the results of the above tests regarding different microorganisms fermenting different sugars differentely, we can exclude few bacterias during diagnosis.
