Separately autoclave cysteine-HCl (as 5% solution) and Na2S·9H2O solutions (as 5% solution) under a N2 atmosphere. Prior to inoculation, add filter-sterile glucose and Na2CO3 solutions, cysteine-HCl, and Na2S·9H2O. Final pH of the complete medium should be 7.0. | | | | | | | | | | *Trace elements solution | | | | Nitrilotriacetic acid (NTA) | 12.8 | g | | | | FeCl3·6H2O | 1.35 | g | | | | MnCl2·4H2O | 0.1 | g | | | | CoCl2·6H2O | 0.024 | g | | | | CaCl2·2H2O | 0.1 | g | | | | ZnCl2 | 0.1 | g | | | | CuCl2·2H2O | 0.025 | g | | | | H3BO3 | 0.01 | g | | | | Na2MoO4·2H2O | 0.024 | g | | | | NaCl | 1 | g | | | | NiCl2·6H2O | 0.12 | g | | | | KAl(SO4)2·12H2O | 0.018 | g | | | | Na2SeO4 | 0.004 | g | | | | Na2WO4 | 0.004 | g | | | | Distilled water | 1 | L | | | | First dissolve nitrilotriacetic acid and adjust pH to 6.5 with NaOH, and then add minerals.
