Preparation
- Dissolve 10.0 g/L tryptone, 5.0 g/L yeast extract, 5.0 g/L NaCl, and 15.0 g/L agar if needed in 1000.0 ml/L distilled water.
- Dissolve 2.0 g/L Na2CO3 separately.
- Adjust the final ALB Medium to pH 8-9.
- Autoclave the basal medium and the Na2CO3 solution separately.
- Aseptically add sterile Na2CO3 to the autoclaved basal medium.
- Use ALB Medium under air containing 5% CO2.
