## Main sol. 1301

0.41	g	KH2PO4	
0.43	g	Na2HPO4	
0.1	g	MgCl2 x 6 H2O	
0.11	g	CaCl2 x 2 H2O	
0.3	g	NaCl	
0.3	g	NH4Cl	
1	ml	**Trace element solution**	
1	ml	**Selenite-tungstate solution**	
0.2	g	Yeast extract	
0.5	ml	Sodium resazurin (0.1% w/v)	
1.5	g	Na2CO3	
1.8	g	D-Glucose	
2	ml	**Wolin's vitamin solution**	
0.3	g	Na2S x 9 H2O	
0.5	g	L-Cysteine HCl x H2O	
1000	ml	Distilled water	

1. Dissolve ingredients (except carbonate, glucose, vitamins and reducing agents) and sparge medium with 80% N2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Dispense medium under same gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. Add glucose, vitamins, sulfide and cysteine from sterile anoxic stock solutions prepared under 100% N2 gas and carbonate from a sterile stock solution prepared under 80% N2 and 20% CO2 gas mixture. Adjust pH of the complete medium to 7.0-7.2, if necessary.


## Trace element solution

0.5	g	Na2-EDTA	
2	g	FeCl2 x 4 H2O	
70	mg	ZnCl2	
100	mg	MnCl2 x 4 H2O	
6	mg	H3BO3	
190	mg	CoCl2 x 6 H2O	
2	mg	CuCl2 x 2 H2O	
10	mg	AlCl3	
24	mg	NiCl2 x 6 H2O	
36	mg	Na2MoO4 x 2 H2O	
1000	ml	Distilled water	

1. First dissolve EDTA in distilled water, adjust pH to 7 using 2 N NaOH and add ferrous chloride. After ferrous chloride has dissolved add remaining compounds.


## Selenite-tungstate solution

0.5	g	NaOH	
3	mg	Na2SeO3 x 5 H2O	
4	mg	Na2WO4 x 2 H2O	
1000	ml	Distilled water

2	mg	Folic acid	
10	mg	Pyridoxine hydrochloride	
5	mg	Thiamine HCl	
5	mg	Riboflavin	
5	mg	Nicotinic acid	
5	mg	Calcium D-(+)-pantothenate	
0.1	mg	Vitamin B12	
5	mg	p-Aminobenzoic acid	
5	mg	(DL)-alpha-Lipoic acid	
1000	ml	Distilled water
