Detailed explanation-1: -Streptomycin is the first discovered aminoglycoside antibiotic, originally isolated from the bacteria Streptomyces griseus. It is now primarily used as part of the multi-drug treatment of pulmonary tuberculosis.

Detailed explanation-2: -Streptomyces griseus is a particular case in point, and is used industrially to produce streptomycin. Streptomycin is a so-called ‘broad spectrum antibiotic’ i.e. active against both Gram positive and Gram negative bacteria, and belongs to the aminoglycoside group of antibiotics.

Detailed explanation-3: -Streptomyces griseus produces the antibiotic streptomycin.

Detailed explanation-4: -griseus, the first Streptomyces to be used for industrial production of an antibiotic-streptomycin, and S. coelicolor, the most widely used in genetic studies. Various strains have been sequenced and their genomes have been mapped (Table 1).

Detailed explanation-5: -So, the correct answer is ‘Streptomycin’
