The above-mentioned components can be modified by adding the various substances in a variety of ways as per the results required so that the rapid and satisfactory growth of the bacterial cell takes place. The final pH of the solutions is adjusted to 7.1 – 7.5 preferably the 7.3 at 25 ☌. It liquefies on heating to 96 ☌ and hardens into a jelly on cooling 40-45 ☌.

⇒ Agar-Agar – It is often called as Agar, is a complex polysaccharide, a carbohydrate consisting of 3, 6-Anhydro-L-galactose and D-galactopyranose, free of nitrogen, produced from various red-purple algae belonging to Gelidium, Gracilaria, Gigastina etc. It must be present in right proportion otherwise it will lead to the lysis of the bacterial cell. ⇒ Sodium Chloride – It maintains the osmotic pressure in the agar medium so that the movement of molecules takes place in and out of the bacterial cell. ⇒ Dipotassium hydrogen phosphate – It acts as the buffer in the medium that helps to maintain the stable pH of the Trypticase Soy Agar (TSA) medium. ⇒ Dextrose – The Dextrose present in the Trypticase Soy Agar (TSA) Medium provides a rich source of carbohydrate for the rapid growth of the Bacterial Cell.

⇒ Papaic Digest of Soybean – Similar to Pancreatic Digest of Casein, the Papaic Digest of Soybean is the Rich source of protein or peptides and nutrients that support the rapid growth of the bacterial cell. ⇒ Pancreatic digest of casein – The Pancreatic Digest of Casein is a rich source of Nutrients, Vitamins, and Nitrogenous substances that support the rapid growth of the bacterial cell. This Solid medium, used in bacteriology laboratory, constitutes the 6 essential components which are described below in detail – The Trypticase Soy Agar medium (TSA), however not commonly employed in routinely in laboratories, is an excellent medium to obtain the discrete colonies of the bacteria present in the specimen or to get the information about cultural characteristics of bacteria on a solid medium, colony morphology and patterns of growth etc. PRINCIPLE OF TRYPTICASE SOY AGAR MEDIUM (TSA) PREPARATION OF NUTRIENT BROTH MEDIUM IN LABORATORY In this article, I’m gonna explain the procedure of preparing Trypticase Soy Agar (TSA) medium in LaboratoryĬheck out the Preparation of Nutrient broth Medium in Laboratory However, there are various types of media available that are based on the requirements of particular bacteria but the Trypticase Soy Agar (TSA) is the best artificial medium that fulfills the basic requirements of almost all types of bacteria and gives a satisfactory and rapid growth of most organisms. those bacteria which can grow easily on any medium and have no special requirements, are the Soybean and Casein Digest supported by various components. those bacteria that have some specific requirement for the growth as well as the Non-Fastidious bacteria i.e. The Tryptone Soy Agar (TSA) contains the magical ingredients that supports almost all types of Fastidious i.e. This media provides all the basic components that are required by the bacterial cell for the rapid growth in the laboratory. The universal culture medium used in the microbiology laboratories that supports the cultivations of almost all types of bacteria is the Trypticase Soy Agar Medium (TSA), also known as the Tryptic soy agar or Tryptone Soya agar. Bacteria need to be cultured in the laboratory for various purposes like identification of the causative agent associated with the pathology, for research purposes, preparations of various vaccines as well as for the productions of certain proteins and enzymes, etc.
