Answer #1

Q. No. 6. Answer :

* The Echerichia coli bacteria is can use citrate as only source of carbon.

* To find out this we can use citrate utilization test.

* some gram negative bacterial species will grow on the surface on the slant but not produce colour change.

* so the gram negative bacterial species are use citrate as only source of carbon.

Q. No 7. Answer :

Triple sugar iron test is one of the microbiology test, it is used to ability to test the microorganisms ability to ferment sugars.

Carbohydrate fermentation tube test :

It is done for ability to find the microorganisms to ferment with the given carbohydrates.

Yes, TSI results for each organism agree with the carbohydrate fermentation tube results.

Because as the definition explained both tests are used to know the ability of bacteria ferment with carbohydrates.
