How is streptomycin recovered?(a) Paper chromatography(b) Hydrophobic

1.	How is streptomycin recovered?(a) Paper chromatography(b) Hydrophobic chromatography(c) Size exclusion chromatography(d) Ion exchange chromatographyThe question was posed to me by my college director while I was bunking the class.Origin of the question is Production of Antibiotics (Isolation of Fermentation Products) in portion Antibiotics & Enzyme Immobilization of Drug Biotechnology
Answer» RIGHT choice is (d) Ion exchange chromatography The best explanation: STREPTOMYCIN is an antibiotic which is used to TREAT a number of bacterial infections. It is an extracellular product so they are removed by adsorption to ion exchange columns in chromatography. The period of operation is short and streptomycin sulfate is obtained in a single fraction with an OVERALL yield of approximately 60 percent at a purity of 400 to 600 UNITS per mg.
