Preparation

  1. 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.
  2. Dissolve 2.0 g/L Na2CO3 separately.
  3. Adjust the final ALB Medium to pH 8-9.
  4. Autoclave the basal medium and the Na2CO3 solution separately.
  5. Aseptically add sterile Na2CO3 to the autoclaved basal medium.
  6. Use ALB Medium under air containing 5% CO2.
