  • 30 g KH2PO4
  • 5 g NaCl
  • 5 g NH4Cl
  • Dissolve the salts in 800 ml water and adjust the pH to 7.2 with NaOH. Add water to a final volume of 1 l and autoclave for 15 minutes at 121 °C.
  • Add the following components for 900 ml of distilled H2O:
    • 20 g Trypton
    • 5 g Bacto Yeast Extract
    • 2 ml of 5 M NaCl
