Solid Media for Microbiology

Agar serves as a solidifying agent that allows for the cultivation and isolation of bacterial colonies on a solid surface.

Agar remains melted until cooled to around 42°C and will melt when heated to near boiling (95°C-100°C).

Petri plates are used to provide a sterile surface on which liquefied agar can solidify, allowing for the growth of microbes.
