Preparation

  1. Sparge medium with 100% N2 gas mixture for 20 min to make it anoxic.
  2. Adjust pH to 6.5-6.8 with 1N H2SO4.
  3. Fill 10 ml of medium in serum bottles (100 ml) under a protective H2/CO2 atmosphere and tightly stopper.
  4. Autoclave at 121 °C for 15 min.
  5. after autoclaving add the following filter-sterilized solutions.
  6. apply xx bar H2/CO2 (80%/20%) + yy % O2 (Note: strain specific conditions need to be applied)
  7. For more details on the medium see the original description (Huber et al. System. Appl. Microbiol. 15:340-351 (1992)).
  8. To 1000.0 ml trace element solution in medium 141 add:
  9. prepared under CO2 in an ice-bath, filter-sterilise
  10. Prepared under N2,autoclave 121°C, 15 min
  11. First dissolve nitrilotriacetic acid and adjust pH to 6.5 with KOH, then add minerals. Adjust final to pH 7.0 with KOH.
