1 Dissolve ingredients (except bicarbonate, vitamins, methanol, cysteine and sulfide), sparge medium with 80% N2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Add and dissolve bicarbonate and adjust pH to 6.5, then distribute under same gas atmosphere into anoxic Hungate-type tubes or serum vials to 30% of their volume and autoclave. After sterilization add methanol (from 50% v/v solution), cysteine and sulfide from sterile anoxic stock solutions autoclaved under 100% N2 gas. Vitamins are prepared under N2 gas atmosphere and sterilized by filtration. Adjust pH of complete medium to 6.5, if necessary. |
