Of the tests you performed, which ones involved the process of fermentation of same carbon source? Explain your answer. The tests performed were cytochrome c oxidase and catalase tests, methyl red, voges-proskauer, cysteine desulferase, indole, sugar fermentation, and MacConkey agar, and citrate test. I think it\'s the sugar fermentation, but I\'m not sure about the \'same carbon source\' part.

Solution

The correct answer is sugar fermentation test.

The carbon sources of bacteria are usually glucose and lactose.

In this test,glucose and lactose along with raffinose,sucrose undergo fermentation.

In this test,acid products which are produced from fermentation of sugar will cause a noticeable colour change in a pH indicator added to the medium.
