1.Streptomycin is obtained from Streptomyces griseus.

Streptomycin is an antibiotic that is produced by the bacterium Streptomyces griseus. Streptomyces species are well-known producers of various antibiotics, and Streptomyces griseus is specifically associated with the production of streptomycin.

Streptomycin is effective against a wide range of bacteria, including both Gram-positive and Gram-negative bacteria. It has been used in the treatment of various bacterial infections, including tuberculosis and certain forms of meningitis.

Therefore, Streptomycin is obtained from Streptomyces griseus.
