In vitro Assessment of Antibiotic Efficacy of streptomycin Isolated from S. griseus Against Selected Bacteria

Manish Kumar, Sushma

Abstract: S. griseus isolated from soil samples was screened for production of streptomycin by plate assay. Identification of streptomycin antibiotic was done by paper chromatography using selected strains of bacteria by measuring the zone of inhibition. Among all the bacterial strains studied; the highest zone of inhibition was measured against E. coli whereas lowest was measured against S. aureus after 24 hrs in nutrient agar media.
