| 1 Dissolve ingredients (except Trypticase peptone, yeast extract, sodium thiosulfate and sulfide), adjust pH to 6.0 and sparge medium with 100% N2 gas for at least 30 min to remove dissolved oxygen. After autoclaving add peptone, yeast extract, thiosulfate and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas. Stock solutions of substrates can be autoclaved with the exception of sodium thiosulfate which should be sterilized by filtration. Prior to inoculation adjust pH of final medium to 6.0. | |||||
