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.
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 ]
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 ).
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.
TSI agar slant results: (from left) preinoculated (as control), P. aeruginosa, E. coli, Salmonella Typhimurium, Shigella flexneri The Triple Sugar Iron (TSI) test is a microbiological test roughly named for its ability to test a microorganism's ability to ferment sugars and to produce hydrogen sulfide.

Peptone water is a microbial growth medium composed of peptic digest of animal tissue and sodium chloride.The pH of the medium is 7.2±0.2 at 25 °C and is rich in tryptophan. [1]
