# 842: HALOANAEROBACTER SALINARIUS MEDIUM ## Main sol. 842 150 g NaCl 15 g MgCl2 x 6 H2O 3 g KCl 0.5 g NH4Cl 0.35 g KH2PO4 0.05 g CaCl2 x 2 H2O 0.1 g Yeast extract 0.5 g Na2S x 9 H2O 2 g NaHCO3 1.2 g Glucose 1 mg Resazurin 1 ml **Trace element solution SL-12 B** 1 ml **Selenite-tungstate solution** 1 ml **Vitamin solution 7** 997 ml Distilled water 1. Final pH 7.2 - 7.4 2. Prepare the medium without yeast extract, Na2S x 9 H2O, NaHCO3, glucose and vitamin solution (prepared as anaerobic, sterile stock solutions). Boil the medium and cool under anaerobic gas mixture of N2:CO2 (80:20). Dispense medium into Hungate tubes or serum bottles using the same gas mixture. Autoclave. Add the remaining components to the medium once it has cooled and check the final pH. ## Selenite-tungstate solution 6 mg Na2SeO3 x 5 H2O 8 mg Na2WO4 x 2 H2O 0.4 g NaOH 1000 ml Distilled water ## Vitamin solution 7 10 mg Biotin 50 mg p-Aminobenzoic acid 50 mg Vitamin B12 100 mg Thiamine 1000 ml Distilled water ## Trace element solution SL-12 B 3 g Na2-EDTA 1.1 g FeSO4 x 7 H2O 190 mg CoCl2 x 6 H2O 50 mg MnCl2 x 2 H2O 42 mg ZnCl2 24 mg NiCl2 x 6 H2O 18 mg Na2MoO4 x 2 H2O 300 mg H3BO3 2 mg CuCl2 x 2 H2O 1000 ml Distilled water 1.
