Preparation Note
Suspend 28.85 g in 1 liter distilled water. Heat to boiling to dissolve the medium completely. Sterilize by autoclaving at 15 lbs pressure (121°C ) for 15 minutes. Cool to 50°C and pour into sterile petri plates. This medium can be made more selective by aseptically adding 0.25 ml of 1% potassium tellurite solution (Cat. No. 17774) to 1 liter molten and cooled medium (45-50°C).
