Solid media is nutrient medium on whcih, when streak with the bacterial sample the bacterial colonies developed. It is commonly used to isolate different bacterial species or to have a pure culture i.e. a culture containing only one type of microorganism. At first R. Koch a German physician used to grow bacterial colony on boiled and sliced potatoes. Eventually he developed the culture media using meat extracts and protein digests and solidify it by using gelatin. Although Gelatin is consumed by many bacterial species. Due to this disadvantage of gelatin Fannie Elishemius Hesse, the wife of Walther Hesse, one of the Koch's assistants suggest using AGAR as solidifying agent. Agar was not attacked by most bacteria and did not melt until reaching a temprature of 100oC. Furthermore once melt it did not solidify until it reached a temprature of 50oC.
