Preparation

  1. Adjust pH to 7.0 using H2SO4.
  2. Prepare the medium under H2 gas and fill 20 ml medium into 100 ml serum bottles and seal with a rubber stopper. Steam/heat the medium in an almost boiling waterbath for 3 hours on each of 3 successive days to sterilize.
  3. Add bicarbonate from a autoclaved and neutralized stock solution.
  4. Check pH and adjust accordingly.
  5. Give an atmosphere of H2/CO2/O2 (78/20/2) with an overpressure of two atmospheres.
  6. First dissolve nitrilotriacetic acid and adjust pH to 6.5 with KOH, then add minerals. Adjust final to pH 7.0 with KOH.
