Preparation

DSMZ Medium 194 sparges Solution A with an 80% N2 and 20% CO2 gas mixture to reach pH below 6, distributes it under the same gas atmosphere into anoxic Hungate-type tubes or serum vials, and autoclaves it.
DSMZ Medium 194 autoclaves Solution B under 80% N2 and 20% CO2, autoclaves Solutions C and E under 100% N2, filter-sterilizes Solution D under 100% N2, then adds Solutions B to E to sterile cooled Solution A in sequence.
DSMZ Medium 194 adjusts the final pH to 7.1-7.4.
DSMZ Medium 194 notes that growth of some strains may be stimulated with 10-20 mg/L sodium dithionite from a freshly prepared anoxic 5% w/v solution sterilized by filtration.
