thoroughly. Filter sterilize.
Preparation of Medium: Add glycerol and the other components,
except glucose solution, egg yolk emulsion, and Malachite Green solu-
tion, to distilled/deionized water and bring volume to 1.0L. Mix thor-
oughly. Gently heat and bring to boiling. Distribute into tubes or flasks.
Autoclave for 15 min at 12 psi pressure–118°C. Cool to 55°C. Asepti-
cally add 100.0mL egg yolk emulsion, 1.0mL glucose solution, and
13.0mL Malachite Green solution. Mix thoroughly. Aseptically dis-
pense into sterile tubes. Allow to solidity as slants.
