Official DSMZ medium: This medium was manually curated by experts from the DSMZ.
* Modification: Omit Na-acetate and add after autoclaving 1.00 ml/l seven vitamins solution (see medium 503) and 0.33 g/l Na-octanoate from anoxic stock solution sterilized by filtration.

1 Solution A is sparged with 80% N2 and 20% CO2 gas mixture to reach a pH below 6 (at least 30 min), then distributed under the same gas atmosphere in anoxic Hungate-type tubes or serum vials and autoclaved. Solution B is autoclaved separately under 80% N2 and 20% CO2 gas atmosphere. Solutions C and E are autoclaved under 100% N2 gas. Solution D is prepared under 100% N2 gas atmosphere and sterilized by filtration. To complete the medium appropriate amounts of solutions B to E are added to the sterile solution A in the sequence as indicated. Final pH of the medium should be 7.1 - 7.4. | |||||
2 Note: Addition of 10 - 20 mg sodium dithionite per liter (e.g. from 5% (w/v) solution, freshly prepared under N2 and filter-sterilized) may stimulate growth of some strains at the beginning. For transfers use 5 - 10% (v/v) inoculum. |
