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.
Best Answer: From cultures of the mold Penicillium chrysogenum, Penicillin is an organic acid. It acts as an antibiotic through lysis of bacterial cell walls, specifically its peptidoglycan layer.Through its attachment to penicillin binding proteins, it can inhibit the synthesis of the bacterial cell wall, thus killing the bacteria.t acts as an antibiotic through lysis of bacterial cell walls, specifically its peptidoglycan layer.
