# 1426: SSE/HD 1:10 MEDIUM


## Main sol. 1426

0.5	g	Peptone	
0.25	g	Yeast extract	
0.1	g	Glucose	
1.95	g	MES (10 mM final concentration)	
500	ml	**SSE (double concentrated)**	
500	ml	Distilled water	

1. Add to 1000 ml of medium after autoclaving: 

1	ml	**Trace element solution SL-10**	
1	ml	**Vitamin solution**	

2. adjust pH to 5.5
3. For solid medium use purified agar (Oxoid LP0028)


## SSE (double concentrated)

0.2938	g	CaCl2 x 2 H2O	
0.1069	g	NH4Cl	
0.2036	g	MgCl2 x 6 H2O	
0.1983	g	(NH4)2SO4	
0.739	g	MgSO4 x 7 H2O	
0.8606	g	CaSO4 x 2 H2O	
0.236	g	Ca(NO3)2 x 4 H2O	
0.424	g	Na NO3	
0.5	ml	KH2PO4 (100 mM solution, 100 mM)	
0.0111	g	FeSO4 x 7 H2O	
0.087	g	K2SO4	
1000	ml	Distilled water	

1. Dissolve by shaking overnight. Sterilize by autoclaving.


## Trace element solution SL-10

10	ml	HCl (25%)	
1.5	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	
24	mg	NiCl2 x 6 H2O	
36	mg	Na2MoO4 x 2 H2O	
990	ml	Distilled water	

1. First dissolve FeCl2 in the HCl, then dilute in water, add and dissolve the other salts. Finally make up to 1000.00 ml.
