Clear zones of suppression of bacterial growth around the individual antibiotic disks are evidence of sensitivity to these antibiotics. Penicillin (Penicillin G) inhibits bacterial growth by inhibiting peptidoglycan synthesis. Streptomycin belongs to the family of aminoglycoside antibiotics, and inhibits bacterial growth by inhibiting protein synthesis. Penicillin-Streptomycin is used for the prevention and elimination of bacterial contaminants in cell culture. General rules for antibiotic storage. Most antibiotics are stable as dry powders. Dissolving the powder in sterile water or other solvents (most frequently, absolute ethanol) exposes the compound to hydrolysis, making the antibiotic more unstable. That’s why antibiotic stocks should be kept in aliquots at -20°C and agar plates should be kept ...
