How Penicillin Was Discovered & Developed | Britannica

Almanac: The discovery of penicillin

Penicillin is hydrolyzed and thereby rendered inactive by penicillinase (also known as β -lactamase ), an enzyme present in some penicillin-resistant bacteria. The mass of this enzyme in Staphylococcus aureus is 29.6 kd . The amount of penicillin hydrolyzed in 1 minute in a 10-ml solution containing 10^-9 g of purified penicillinase was measured as a function of the concentration of penicillin. Assume that the concentration of penicillin does not change appreciably during the assay. (a) Plot V0
