![]() ![]() ![]() ![]() 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 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 Broth 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 Broth (TSB) medium. ⇒ Dextrose – The Dextrose present in the Trypticase Soy Broth (TSB) 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 Liquid medium, used in bacteriology laboratory, constitutes the 5 essential components which are described below in detail – The Trypticase Soy Broth medium (TSB), 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 in a liquid medium, colony morphology and patterns of growth etc. PRINCIPLE OF TRYPTICASE SOY BROTH MEDIUM (TSB) However, there are various types of media available that are based on the requirements of particular bacteria but the Trypticase Soy Broth (TSB) 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 Broth (TSB) contains the magical ingredients that supports almost all types of Fastidious i.e. PREPARATION OF TRYPTICASE SOY AGAR MEDIUM (TSA) a.k.a TRYPTIC SOYA AGAR OR TRYPTONE SOYA AGAR IN LABORATORY In this article, I’m gonna explain the procedure of preparing Trypticase Soy Broth (TSB) medium in LaboratoryĬheck out the Preparation of Trypticase Soy Agar (TSA) medium in Laboratory 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 (TSA) and the Trypticase Soy Broth Medium (TSB), also known as the Tryptic Soy Broth or Tryptone Soya Broth. In Microbiology laboratory, Bacteria need to be cultured in the 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. PRECAUTIONS TO BE TAKEN WHILE PREPARING TRYPTICASE SOY BROTH (TSB) MEDIUM IN LABORATORY ![]()
