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.
Solution occurs in 14 other media (first defined in Medium 88).
