Cultivation of fastidious aerobic and anaerobic bacteria. ||Description: |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 studies.||Appearance:|Beige homogeneous, free flowing powder||Solubility:|Light to medium amber, clear, complete||pH:|As Reported||Microbiological Analysis:|Escherichia coli ATCC 25922: Very Good to Excellent|Neisseria meningitides ATCC 13090: Faair to Good|Staphylococcus aureus ATCC 25923: Good to Excellent |Streptococcus pneumoniae ATCC 6305: Good to Excellent|Streptococcus pyogenes ATCC 19615: Good to Excellent
