Question

Quizplus · Accepted Answer

Agar has chemical and physical properties that make it almost ideal for solidifying media. It remains solid at temperatures up to 45°C, but can be melted at temperatures above 85°C. Additionally, it is not degraded by most bacteria and provides a relatively inert matrix for bacterial growth.
