2 Distribute the medium into culture vessels (leave >80% volume gas phase) under a N2-CO2 (4:1) gas mixture and seal with butyl rubber stoppers. Pressurize the culture vessels to 200 kPa with methane gas. Finally add O2 gas to make up 2% O2 concentration in the gas phase. Readjust pH to 6.0 - 6.3, if necessary. |
