Preparation

  1. Mix components thoroughly and adjust pH to 7.5. Distribute the medium in culture vessels (e.g., 10 ml in Balch-type tubes), flush with N2 and seal with butyl rubber stoppers. Autoclave. After cooling, add per liter the following solution (autoclaved or *filter-sterilized):
  2. After inoculation, add sterile pure acetylene gas, made from calcium carbide and water, to the gas phase (the first time, 0.5% volume of the gas phase: the next day, 1.0% volume: increase each day until 2.5% volume is reached).
