Question

pH range required for streptomycin production is __________

(a) 7-8

(b) 5-8

(c) 4-5

(d) 9-10

The question was asked in an online interview.

My question comes from Production of Antibiotics (Isolation of Fermentation Products) in chapter Antibiotics & Enzyme Immobilization of Drug Biotechnology

Answer 1

Right answer is (a) 7-8

To explain: The optimum temperature for fermentation should be in the range of 25 to 30°C. The optimum pH range should be in the range of 7.0 and 8.0. High rate of streptomycin production occurs in the pH range of 7.6 to 8.0.
