1 Dissolve ingredients (except bicarbonate, glucose, vitamins and reducing agents), then sparge medium with 100% CO2 gas for 30 - 45 min to make it anoxic. Add solid bicarbonate, adjust pH to 6.8 - 7.0 and dispense medium under 100% CO2 gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. Add glucose, vitamins (sterilized by filtration), cysteine and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas. The final pH of the medium should be 7.0.

1 First dissolve nitrilotriacetic acid and adjust pH to 6.5 with KOH, then add minerals. Adjust final to pH 7.0 with KOH.
Solution occurs in 28 other media (first defined in Medium 1310).
1 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.
Solution occurs in 357 other media (first defined in Medium 141).
