Adjust pH of the medium to 7.0-7.2, if necessary. Dispense the medium into culture vessels (e.g., 100 ml in 120 ml-serum bottles) under the same gas mixture and seal with butyl rubber stoppers or Teflon-lined stoppers. Then, anaerobically add per liter the following solution:
Tetrachloroethene  60.0     μl
Dissolve tetrachloroethene with ultrasound. Autoclave in a closed basket. Do not remove the culture vessels from autoclave before temperature of the media has reached below 70C.
Finally, add per liter the following solution from an anaerobic stock (filter-sterilized):
Trace vitamins (see Medium No. 197)  10.0     ml
