3	ml	**Iron stock solution 2.0 g/L**	
5	ml	**Vitamine mixture**	
10	ml	**Glucose stock 20%**	

1. fill to 1 Liter with H2O (autoclaved)
2. anaerobize with nitrogen, can be stored anaerobically


## Salt mix 10x

50	g/l	Na2HPO4	
20	g/l	NaH2PO4 x H2O	
9	g/l	KH2PO4	
9	g/l	NaCl	

1. autoclave


## CasAA mix 5x

50	g/l	Casamino acids	
2.5	g/l	L-Cysteine	
0.5	g/l	L-Tryptophan	

1. pH should be between 6-7, may depend on the casamino acid and cysteine lot
2. steril filtration, store as batches at -20°C


## Trace salt mix 100x

4	g/l	(NH4)2SO4	
2.6	g/l	CaCl2 x 2 H2O
