What is the value of agar in isolating bacteria from mixed culture?
Angelina Fanny Hesse made the isolation of bacteria possible by suggesting the use of agar-agar. In the early 1880's Hitchens and Leikind suggested that 'plain agar' be referred to as 'Frau Hesse's medium' to acknowledge her forgotten 'service to science and to humanity.' Perhaps it's finally time that we remember Frau Hesse and celebrate all the ignored 'bead collectors' working in the laboratories and kitchens that make science possible.Agar is actually an inert but great medium for growing microorganisms. It will grow the largest number of different types of microbes - fungi and bacteria. Agar is a general purpose medium supporting growth of a wide range of non-fastidious organisms.Yet, not all bacteria can grow on it. Some find it too rich, and others find it deficient. An example of a fastidious organism is Neisseria gonorrhoeae, which requires blood or hemoglobin and several amino acids and vitamins in order to grow.You would then know that the organism you are looking at can't be gonorrhea since it didn't grow.

How do you make semi solid media?
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.

Who invented agar in microbiology?
About a year later, in 1882, agar was first used as a solidifying agent. It had been discovered by a Japanese innkeeper, Minora Tarazaemon. The story goes that he threw out extra seaweed soup and discovered the next day that it had gelled during the cold winter night. Agar had been used by the East Indies Dutch to make jellies and jams. Fannie Eilshemius Hesse, the New Jersey -- born wife of Walther Hesse, one of Koch's assistants, had learned of agar from a Dutch acquaintance and suggested its use when she heard of the difficulties with gelatin. Agar -- solidified medium was an instant success and continues to be essential in all areas of microbiology.
