Description and Uses
Benzylpenicillin potassiumwas the first crystalline penicillin produced on an industrial scale , . It is produced in the pure state by the addition of phenylacetate to a culture of Penicillium chrysogenum. The crystalline benzylpenicillin potassium contains 1598 U/mg.
Penicillin G is a narrow spectrum antibiotic derived from Streptococcus pneumoniae. Penicillin G potassium salt is used as a cell culture additive as an antibiotics. Use to inhibit the synthesis of bacterial cell walls by inhibition of the cell wall peptidoglycan chain cross-lining. It is the drug of choice for groups A, B, C and G streptococci, nonenterococcal group D streptococci, viridians group streptococci, and non-penicillinase producing staphylococcus. The potassium salt has been used to study murosomes of staphylococci and the penicillin-induced lysis of Streptococcus mutans.
