Streptomycin yields in production fermenters respond strongly to high aeration and agitation. Optimum temperature 25-30°C. Optimum pH range from 7 and 8. Fermentation lasts approx. five to seven days. Streptomycin yields probably in excess of 1200 mg per milliliter.In contrast, brief treatment with streptomycin failed to affect subsequent killing by penicillin. These findings suggest that the synergism of penicillin with streptomycin depends on the damaging effect of penicillin on the cell membrane, which promotes further damage by streptomycin and increases its subsequent access to intracellular sites.Streptomycin was originally purified from Streptomyces griseus.

The higher the time of the material storage in a refrigerator, the lower the penicillin level in the tissues.Antibiotics are produced industrially by a process of fermentation, where the source microorganism is grown in large containers (100,000 – 150,000 liters or more) containing a liquid growth medium. Oxygen concentration, temperature, pH, and nutrient levels must be optimal and are closely monitored and adjusted if necessary.These findings suggest that the synergism of penicillin with streptomycin depends on the damaging effect of penicillin on the cell membrane, which promotes further damage by streptomycin and increases its subsequent access to intracellular sites.
