Question

Streptomyces griseus produces an antibiotic known as:
A. Terramycin
B. Neomycin
C. Chloramphenicol
D. Streptomycin

Answer 1

Hint: One can define Streptomyces griseus as a species under the phylum of bacteria in the genus of Streptomyces which are commonly found in soil. The sediments of deep-sea can report a few strains. The Streptomyces griseus has high GC content. Thus it is a Gram-positive bacterium. The producers of antibiotics are the name given to the griseus strains.

Complete answer: Streptomycin is one of the antibiotics. It is generally used in the preparation of medicines which help in inhibiting the development of microbes. The wide spectrum antibiotic which works against both grams negative and gram-positive bacteria can be known as Streptomycin.
One of the antibiotics which is used in the preparation of the medicines which help in the treatment of several bacterial infections is called Chloramphenicol.
One can say that Neomycin is an aminoglycoside antibiotic that is typically found in many topical medications just like creams, ointments, and eye drops.
The second of the wide spectrum group of tetracyclines of antibiotics to be discovered is called Oxytetracycline. The Oxytetracycline generally works by being intrusive with the aptitude of bacteria to produce essential proteins.
So, the correct answer is (D) 'Streptomycin.'

Note: The Streptomyces griseus are also commercially significant secondary metabolites. The strains of the Streptomyces griseus are known to be the producers of 32 different structural types of bioactive compounds. It is said that the Streptomycin can give rise to a subset of other antibiotics like Streptomyces griseus. The medicines which are made by Chloramphenicol include the eye ointment to treat conjunctivitis.
