Question

Which of the following method can
used to determine the number of
bacteria quantitatively?​

Answer 1

Answer:

Which of the following method can be used to determine the number of bacteria quantitatively?

Explanation: Due to a higher degree of dilution, pour-plate and spread-plate techniques may be performed in a quantitative manner to determine the number of bacteria present in a specimen.

Answer 2

Answer :

Pour-plate and spread-plate techniques is the method used to determine the number of bacteria quantitively.

Explanation :

Pour-plate and spread-plate procedures can be used quantitatively to count the quantity of bacteria present in a material due to a higher degree of dilution.

Since Robert Koch's time, the pour Plate Method technique has been widely used. It was developed in his lab. Microorganisms that are facultative, microaerophilic, and anaerobic can be treated with this approach. It is straightforward, less resource-intensive, affordable, easy, and requires just that the sample be in liquid or suspension.

Spread plate technique includes spreading a small amount of germs suspended in a solution on a plate using a spreader with a smooth surface made of metal or glass that has been sanitized. For the agar to more easily absorb the bacteria, the plate must be dry and at room temperature.
