| 1 Dissolve ingredients and adjust pH to 2.0 with 10 N H2SO4. Sterilize the medium by filtration. Alternatively, autoclave separately the basal medium (pH adjusted to 2.0) and the ferrous sulfate (8.00 g FeSO4 x 7 H2O in 50 ml 0.1 N H2SO4, pH not adjusted, in a sealed vessel under nitrogen gas atmosphere). | |||||
