penicillin
The antibiotic agent obtained from cultures of the mould Penicillium notatum ( a genus of ascetomycetous fungi, including several of the common moulds); hence, any of a group of antibiotics that are all derivatives of 6-amino-penicillanic acid in which a radical replaces one of the amino hydrogen atoms, some being acids produced naturally by the growth of various moulds of the genera Penicillium and Aspergillus, whilst others are acids, salts, or esters prepared synthetically from these; they are active against many kinds of bacteria but virtually harmless to persons not allergic to them
