Trypticase Soy Broth (Soybean-Casein Digest Medium) is a general purpose medium used in qualitative procedures for the cultivation of fastidious and non-fastidious microorganisms from a variety of clinical and nonclinical specimens. This variety of media helps isolate and cultivate tubercle bacilli and fungi. Adjustments to pH should be made using 1N HCl or 1N NaOH to reach a final target pH of 7.3 ± 0.2 at 25 ☌ (77 ☏). BD Mycoflask sterile, disposable and ready-to-use BD BBL culture media are prepared in the special BD Mycoflask. To prepare 1 liter of TSB, the following ingredients are dissolved under gentle heat. TSB is frequently used in commercial diagnostics in conjunction with the additive sodium thioglycolate which promotes growth of anaerobes. One of the components of Tryptic soy broth is Phytone Archived at the Wayback Machine, which is an enzymatic digest of soybean meal. Its agar counterpart is tryptic soy agar (TSA). It is a complex, general purpose medium that is routinely used to grow certain pathogenic bacteria, which tend to have high nutritional requirements (i.e., they are fastidious). Tryptic soy broth or Trypticase soy broth (frequently abbreviated as TSB) is used in microbiology laboratories as a culture broth to grow aerobic bacteria.
