Nutrient broth is a general purpose medium that can be used to cultivate different variety of both fastidious and non-fastidious microorganisms.

Nutrient broth is known to contain or compose of simple peptone and a beef extract.

It is known to be used for bacteria that will not form colonies  on a solid surface.

Nutrient broth can be prepared through this following steps

* Add 13g of nutrient broth powder  in 1L of distilled water.

* Mix and dissolve them completely.

* Pour them into the final containers (eg. conical flask)

* Sterilize by autoclaving at 121°C for 15 minutes.

In this case, since the 100 ml  and 1000 ml is prepared using the same method, it is expected to have the same number of cells in the same volume of the broth.
