What are the advantages of liquid media for bacterial growth?

There are various advantages of liquid media for bacterial growth. One advantage is that liquid media facilitates a consistent environment for bacterial growth. It also can be easily sterilized using ultra-filtration to eliminate bacteria during the cultivation process. 

Liquid media is a type of broth. Broths are utilized to observe growth patterns in a liquid medium and are particularly useful for specific types of inoculations and metabolic tests. They also serve as the preferred method for cultivating many types of bacteria. Another pro is that liquid media also serves to assess an organism's ability to ferment specific carbohydrates. Additionally, bacterial growth in liquid broth is facilitated under different oxygen levels, as the availability of oxygen diminishes with increasing depth within the broth.
