The Discovery and Research of Penicillin Alexander Fleming’s discovery of penicillin while examining a stray mold in his London laboratory in 1928‚ and its eventual development by Howard Florey and Ernst Chain at Oxford University‚ created a major break through to another world of antibiotics and medicine. Antibiotics like penicillin have become the most important family of drugs of this era. During the 1940’s (World War 2) penicillin became a life saving drug to thousands of soldier’s‚ it also

Penicillin V is a first-generation penicillin used to treat infections generally caused by gram-positive bacteria. Penicillin V consists of 16 carbons‚ 18 hydrogens‚ two nitrogen‚ five oxygens and a sulfur atom. The beta-lactam group is the ring composed of two nitrogen‚ a sulfur atom‚ and an oxygen double-bound to a carbon. Penicillin works by bursting a bacteria’s cell wall; this is done by inhibiting the proteins that link peptidoglycans together in the cell wall‚ which prevents the bacteria from

it "penicillin‚" after the mold that produced it. Thinking he had found an enzyme more powerful than lysozyme‚ Fleming decided to investigate further. What he found out‚ though‚ was that it was not an enzyme at all‚ but an antibiotic -- one of the first antibiotics to be discovered. Further development of the substance was not a one-man operation‚ as his previous efforts had been‚ so Fleming recruited two young researchers. The three men unfortunately failed to stabilize and purify penicillin‚ but
