Preparation

  1. Mix the base components with Trace minerals and 0.1% Na2SeO3 solution and bring the volume to 1.0 L.
  2. Adjust the base medium to pH 7.0.
  3. Dispense the medium into culture vessels under N2 gas, for example 10 ml medium in Hungate tubes, and seal with butyl rubber stoppers.
  4. Autoclave at 121 degrees C for 15 min.
  5. Cool after autoclaving.
  6. Aseptically and anaerobically add filter-sterilized Trace vitamins and 1 M Sodium thiosulfate stocks per liter.
