1 Dissolve ingredients (except bicarbonate, phosphate-buffer, lactose, vitamins, cysteine and sulfide), then sparge medium with 80% N2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Dispense medium under same gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. After sterilization add phosphate-buffer, lactose, cysteine and sulfide from sterile anoxic stock solutions autoclaved under 100% N2 gas and bicarbonate from a sterile anoxic stock solution prepared under 80% N2 and 20% CO2 gas mixture. Vitamins are prepared under N2 gas atmosphere and sterilized by filtration. Adjust pH of complete medium to 6.5, if necessary. | |||||
