You are given a 1 liter bacterial culture in exponential stage of growth. The generation time of the bacteria is known to be 30
nydimaria [60]

Answer:

Option-A

Explanation:

A bacteria divides by binary fission which divides a parent bacteria into the two daughter cells and generation time refers to the average time difference between two consecutive generations.

The bacterial cell grows by the exponential function that is by 2^{number of generation} x initial population of bacteria.

In the given question,

<u>Initial population</u>

the initial population of bacteria - 2x 10³ per ml

So per liter, the bacterial population will be 2 x 10 ⁶

<u>Generation time</u>

1 generation time of bacteria is 30 min.

so 5 hours will have- <u> </u>\frac{300}{30}= 10 generations

<u>New bacterial population</u>

Using formula<u>  </u>2^{number of generation} x initial population of bacteria

2^{10} x (2 x 10⁶)

= 1048 x (2 x 10⁶)

2048 x 10⁶

Thus, Option-A is the correct answer.
