Penicillin is a widely used antibiotic prescribed to treat staphylococci and streptococci bacterial infections. Penicillin belongs to the beta-lactam family of antibiotics, the members of which use a similar mechanism of action to inhibit bacterial cell growth that eventually kills the bacteria. Bacteria cells are surrounded by a protective envelope called the cell wall.
The hydrolysis instead is simply achieved by the use of penicillin acylase. The use of this enzyme is one of the earliest successful processes involving immobilized enzymes and may be reused over 100 times. The penicillin G acylase can be used in the reverse of the reaction as shown in the schematics below.verview. Benzylpenicillin (penicillin G) and phenoxymethylpenicillin (penicillin V) are produced by fermentation and are the foundation for a range of synthetic antibiotics.
