Preparation
- Dispense the medium into culture vessels and seal with butyl rubber stoppers.
- Autoclave at 121 C for 15 minutes.
- Cool to room temperature.
- Adjust pH to 7.0 with sterile pH-adjusting agent by syringe without opening the vessel.
- Filter-sterilize high-purity methane gas.
- Before inoculation, aseptically add methane to an approximately 1:4 methane-to-air headspace.
