Why Is Agar Used as a Solidifying Agent instead of Gelatin?

Answer

Agar is used as a solidifying agent instead of gelatin because it keeps the bacteria solid during its growth. In addition, only few microbes are able to degrade agar; most don't. However, though gelatin is able to solidify medium, it easily turns into liquid at room temperature because gelatin has low melting point.
