Penicillin is active against ____________(a) Gram +ve bacteria(b) Gram

1.	Penicillin is active against ____________(a) Gram +ve bacteria(b) Gram-ve bacteria(c) All virus(d) All bacteriaI have been asked this question in class test.The origin of the question is Production of Antibiotics (Isolation of Fermentation Products) in division Antibiotics & Enzyme Immobilization of Drug Biotechnology
Answer» Right ANSWER is (a) GRAM +ve bacteria Explanation: First discovered by Alexander Fleming in 1929. Natural penicillin is active against a variety of gram +ve bacteria ORGANISMS. They are labile in acids and become inactive when its beta-lactam ring is cleaved by beta-lactamase ENZYME.
