AGAR Contents

[IB Dip]

I currently conducting an experiment, but I need to know the exact
concentrations of the substances in nutrient agar, especially the
concentrations of Sulfur, Iron ( or Ferrous Sulfate ), Potasium ( Potasium
Sulfate ), and Magnesium ( MgSO4 ).  Any help please e-mail me as
ibdip at aol.com.

Thanks
