| 1 Dissolve ingredients (except cysteine, bicarbonate, xylose, thiosulfate and sulfide), then sparge medium with 80% N2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Add and dissolve cysteine, adjust pH to 6.5, then dispense medium under 80% N2 and 20% CO2 gas mixture into anoxic Hungate-type tubes or serum vials to 30% of their volume and autoclave. After sterilization add thiosulfate and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas and bicarbonate from a sterile anoxic stock solution prepared under 80% N2 and 20% CO2 gas mixture. Xylose is prepared under 100% N2 gas and sterilized by filtration. Adjust pH of complete medium to 7.0 - 7.2, if necessary. | |||||
