1 Sparge solution A with 80% H2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic, then dispense under same gas atmosphere into anoxic serum vials (e.g., 9 ml medium in 50 ml bottle). Pressurize closed bottles with 80% H2 and 20% CO2 gas mixture to 0.5 bar overpressure and autoclave. Solution B is autoclaved separately under 80% N2 and 20% CO2 gas atmosphere. Solutions C, D and F are autoclave under 100% N2 gas atmosphere.
2 Solution E is prepared under 100% N2 gas atmosphere and sterilized by filtration. Prepare solution G by filling 13.5 ml hexadecane into a 50 ml serum bottle, then sparge with 100% N2 gas to make it anoxic and autoclave. Add 1.50 ml anoxic autoclaved tetrachloroethene to the sterile anoxic hexadecane solution by syringe. To complete the medium add appropriate amounts of solutions B to F to the sterile solution A in the sequence as indicated. The pH of the medium before inoculation should be at 7.2.
3 Add solution G only after inoculation of the medium!
