Preparation
- Dissolve ingredients (except bicarbonate, cellobiose, yeast extract, cysteine and DTT), bring medium to the boil, then cool to room temperature under 100% CO2 gas atmosphere. Add the bicarbonate and equilibrate the medium with the CO2 gas to pH 6.8. Distribute under 100% CO2 gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. Thereafter, add cellobiose, yeast extract, cysteine and DTT from sterile anoxic stock solutions prepared under 100% N2 gas atmosphere. Cellobiose has to be sterilzed by filtration. Adjust pH of complete medium to 6.7 - 6.8, if necessary.
- Rumen fluid from cow or sheep (obtained from fistulated animals or abattoir refuse) is filtered through muslin, autoclaved at 121°C for 15 min and then centrifuged at 27,000 g for 20 min. The supernatant is made anoxic by sparging with 100% N2 gas for 15 min, dispensed under same gas atmosphere into anoxic serum vials to 30% of volume and then stored frozen at -20°C.
