Streptomycin was isolated from Streptomyces griseus. It acts bacteriostatic at low concentrations and bactericidal at higher concentrations against mycobacteria and gram negative bacteria. It is less active against gram positve bacteria. Like other antibiotics, streptomyicin does not act on non-proliferating microorganism. Streptomycin leads to reading error during translation due to the interaction with 23S RNA of the 30S ribosomes.
