Mix meat, water and NaOH and bring to a boil with stirring. Cool to room temperature, skim fat from surface, and filter, retaining both meat particles and filtrate. To filtrate, add sufficient distilled water to restore volumn to 1.0 L. To this filtrate, add trypticase peptone, yeast extract, K2HPO4, resazurin solution and agar (if necessary). Boil and cool medium under 80% N2, 10% CO2, and 10% H2, then add Cysteine-HCl, Hemin solution and Vitamin K1 solution. Adjust pH to 7.0. Anaerobically dispense 7 mL into tubes containing meat particles (1 part meat to 5 parts fluid) under the same gas phase.
Hemin solution:
Dissolve 50 mg hemin in 1mL 1N NaOH, make up to 100 mL with distilled water. Store refrigerated.

Vitamin K1 solution:
Dissolve 0.15 mL of Vitamin K1 in 30 mL of 95% ethanol and filter sterile. Keep Vitamin K1 solution under refrigeration. Store in brown bottle.
