What is pennacillian?

Answer 1

Penicillin is a group of antibiotics derived from the Penicillium fungi, particularly Penicillium chrysogenum. Discovered in 1928 by Alexander Fleming, it was the first true antibiotic and has been widely used to treat bacterial infections. Penicillin works by inhibiting the synthesis of bacterial cell walls, leading to cell lysis and death. It is effective against a variety of Gram-positive bacteria and some Gram-negative bacteria.
