Tryptic soy broth or Trypticase soy broth (frequently abbreviated as TSB) is used in microbiology laboratories as a culture broth to grow aerobic and facultative anaerobic bacteria. It is a general purpose medium that is routinely used to grow bacteria which tend to have high nutritional requirements (i.e., they are fastidious ).
Tryptone is the assortment of peptides formed by the digestion of casein by the protease trypsin. [ 1 ] Tryptone is commonly used in microbiology to produce lysogeny broth (LB) for the growth of E. coli and other microorganisms. [ 2 ]
Rappaport-Vassiliadis soya peptone broth (RVS broth) is used as an enrichment growth medium for the isolation of Salmonella species. [1] It is not recommended for the enrichment of Salmonella Typhi or Paratyphi, which is inhibited due to the malachite green in RVS broth. [2] It is an alternative to selenite broth.
Colonies of Micrococcus luteus on Tryptic Soy Agar. Cultivation 48 hours, 37°C. Trypticase soy agar or Tryptic soy agar (TSA) is a growth media for the culturing of moderately to non fastidious bacteria. It is a general-purpose, non-selective media providing enough nutrients to allow for a wide variety of microorganisms to grow.
Lauryl tryptose broth (LTB) is a selective growth medium for coliforms. [1] Lauryl tryptose broth is used for the most probable number test of coliforms in waters, effluent or sewage. It acts as a confirmation test for lactose fermentation with gas production. Sodium lauryl sulfate inhibits organisms other than coliforms.
Super Optimal Broth (SOB medium) is a nutrient-rich bacterial growth medium used for microbiological culture, generally of Escherichia coli. This nutrient-rich microbial broth contains peptides , amino acids , water soluble vitamins and glucose in a low-salt formulation.
The fluorescent compound is sensitive to the presence of oxygen dissolved in the broth. Initially, the large amount of dissolved oxygen quenches emissions from the compound and little fluorescence can be detected. Later, actively respiring microorganisms consume the oxygen and allow the fluorescence to be detected.
