The nutrient medium is jelly-like.

Nutrient media can be classified according to various criteria. One of the important criteria is consistency. Many culture media have a specific consistency, which may depend on the content of certain components such as water, agar and various substances.

One of the special types of nutrient media is a gelling nutrient medium. The gelling medium is a dense material whose consistency is due to the high gelatin content. This nutrient medium is used to determine the activity of proteolytic microorganisms - bacteria that decompose proteins in the environment.
