# 792b: CAMINIBACTER MEDIATLANTICUS MEDIUM


## Main sol. 792b

989	ml	**Solution A**	
10	ml	**Solution B**	
10	ml	**Solution C**	

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., 20 ml medium in 100 ml bottles) and autoclave. Solution B is autoclaved separately under 80% N2 and 20% CO2 gas mixture and solution C is autoclaved under 100% N2 gas. To complete the medium appropriate amounts of solutions B and C are added to solution A. Adjust pH of the complete medium to 5.7.
2. After inoculation pressurize vials to 2 bar overpressure with sterile 80% H2 and 20% CO2 gas mixture.
3. Note: Solution A has to be prepared freshly. It cannot be stored for a long period of time.
