Penicillin antibiotics are used to treat treat urinary tract infections, upper respiratory tract infections, lower respiratory infections, skin infections, bacterial infections, gastrointestinal infections, meningitis, and pneumonia. They work by killing the bacteria that is causing the infection.
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.
