Agar Agar as a culture media is widely used for practically all pathogenic and nonpathogenic bacteria and fungi because it is not easy to metabolise and has a good gel firmness, elasticity, clarity and stability. Because of its high gellifying power and its vegetable origin, Agar Agar constitutes a natural non-toxic matrix for the formation of culture media in Microbiology.
