# J1076: ALKALIPHILUS LACT MEDIUM ## Main sol. J1076 20 g NaCl 1 g NH4Cl 0.1 g KH2PO4 0.1 g K2HPO4 0.1 g KCl 0.1 g MgCl2 x 6 H2O 3 g Tris base 3 g Na2S2O3 x 5 H2O 1 ml **Trace element solution** 1 mg Resazurin 950 ml Distilled water 1. Mix components thoroughly, adjust pH to 9.0 with NaOH and autoclave under a N2 atmosphere. After cooling, replace the gas phase with a N2-CO2 (4:1, v/v) gas mixture. Add the following solutions from sterile anaerobic stocks (autoclaved and stored under a N2 atmosphere): 10 ml Yeast extract (w/v, 10%) 20 ml Maltose (0.5 M) 20 ml Na2CO3 (8%) 6 ml Na2S x 9 H2O (5%) 2. Check final pH be around 8.2. ## Trace element solution 12.5 ml HCl (25%) 2.1 g FeSO4 x 7 H2O 30 mg H3BO3 100 mg MnCl2 x 4 H2O 190 mg CoCl2 x 6 H2O 24 mg NiCl2 x 6 H2O 2 mg CuCl2 x 2 H2O 144 mg ZnSO4 x 7 H2O 36 mg Na2MoO4 x 2 H2O 987 ml Distilled water
