Cultivation of fastidious aerobic and anaerobic bacteria.
Brain Heart Infusion Broth without Dextrose is a modification of the media described by Rosenow and Hayden in which infusion from calf brains has replaced the brain tissue and disodium phosphate has replaced the calcium carbonate buffer. The addition of 0.1% agar can be used to lower oxygen tension to enhance the growth of anaerobic organisms. Brain Heart Infusion Broth without Dextrose is a basal medium used with added carbohydrates for fermentation studie
