| Preparation Note: | 1. Suspend 40 g in 1L of distilled water. 2. Heat to boiling while stirring to dissolve. 3. Autoclave for 15 minutes at 121°C. 4. Cool to 50°C prior to dispensing into sterile petri dishes. To prepare the medium of Luria and Burrows: Add 1 g glucose to medium and proceed with preparation instructions above. To prepare the medium of Luria, Adams and Ting (also known as LC agar): Aseptically add 25 ml of sterile 0.1 M calcium chloride after autoclaving. |
| Preparation Note: | Add 40g powder to 1L water. Heat to boiling while stirring to dissolve powder. Autoclave for 15 minutes at 121C to sterilize. Allow to cool slightly before making additions, such as antibiotics (if desired). |
