Brain heart infusion media made from Difco powdered media. Brain heart infusion (BHI) is a growth medium for growing microorganisms. It is a nutrient-rich medium, and can therefore be used to culture a variety of fastidious organisms.
This pepsic peptone was developed by DIFCO (Digestive Ferments Company) during the First World War for producing bacterial toxins for vaccine production. [ 15 ] Fort development of red-brick colonies of GBS in granada medium it is necessary the presence of the peptide Ile-Ala-Arg-Arg-His-Pro-Tyr-Phe in the culture medium.

Nutrient broth has the same composition, but lacks agar. [ 2 ] [ 3 ] These ingredients are combined and boiled for approximately one minute to ensure they are mixed and then sterilized by autoclaving, typically at 121 °C (250 °F) for 15 minutes.
The exact composition of the growth medium varies, but aerobic bottles use a broth that is enriched with nutrients, such as brain-heart infusion or trypticase soy broth, [34] and anaerobic bottles typically contain a reducing agent such as thioglycollate. The empty space in an anaerobic bottle is filled with a gas mixture that does not contain ...
