# Nutrient agar plate

## What is this medium used for?  

Nutrient agar is a general-purpose, nutrient medium used for the cultivation of microbes. It is frequently used for isolation and purification of cultures. As we are using it here, it can also be used as a means for producing the bacterial lawns needed for [antibiotic sensitivity tests](https://vumicro.com/docs/antibiotic-susceptibility-tests/).  In actuality, antibiotic sensitivity testing is typically performed on media specially formulated for that purpose.

## What is the content of this medium?  

Nutrient agar consists of heat-stable digestive products of proteins (called peptones) and beef extract. Both of these provide amino acids, minerals, and other nutrients used by a wide variety of bacteria for growth. In addition, it contains agar as a solidifying agent.
