Schaedler Broth was first described by Schaedler et al. as an enriched medium for the isolation of anaerobes from mixed bacteria flora from the gastrointestinal track of mice. Mata et al., substituting Trypto Soy Broth for casein digest peptone in the Schaedler formulation, found that this medium gave excellent recovery of anaerobic and microaerophilic organisms from human fecal and gastrointestinal specimens. Schaedler Broth gave the highest rate of growth and response of anaerobic bacteria of nine broth media studied by Stalons et al.. General growth requirements are supplied by Trypto Soy Broth, dipeptone, yeast extract and dextrose. Hemin and cystine are added for specific requirements of some anaerobes. Blood and other enrichments may be added to enhance growth characteristics.||Appearence:|Light tan, homogeneous, free flowing powder||Solubility:|Light to middle amber, clear to light precipitate||pH:|7.6± 0.2||Microbiological Analysis:|Bacteroides vulgatus ATCC 8482: Growth|Clostridium perfringens ATCC 13124: Growth|Clostridium novyi ATCC 7659: Growth|Staphylococcus aureus ATCC 25923: Growth|Streptococcus pyogenes ATCC19615: Growth||Important Note: This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications without the expressed written authorization of United States Biological.
