Known by it's basic chemical structure as a beta-lactam fuzed to a thiazolidine ring, this stuff was developed commercially from a strain growing on a grapefruit in a market in Peoria, Ill. Most children recognize it by its bananna or cherry flavoring. What is it?

It is penicillin, but not from the original discovery. This strain allowed more production of the desired drug. http://books.google.com/books?id=sQ-D7LPZzVoC&pg=PA243&lpg=PA243&dq=mold+on+a+strain+growing+on+a+grapefruit+in+a+market+in+Peoria,+Il.&source=bl&ots=HcBOmnieGA&sig=eVaj6cOR9xMVM7kwoHy9ZEb3F9k&hl=en&sa=X&ei=WLLQU8qkEuW58gGrzICYDA&ved=0CCcQ6AEwAQ#v=onepage&q=mold%20on%20a%20strain%20growing%20on%20a%20grapefruit%20in%20a%20market%20in%20Peoria%2C%20Il.&f=false

The Penicillins and cephalosporins are all good antibiotics. Most Antibiotics are effective because they inhibit the biosynthesis of vital parts of the bacteria's cells walls. Some bacteria have become resistant to certain antiobiotics by producing a specific enzyme called a beta-lactamase. AUGMENTTIN is an antiobitic which contains a beta-lactamase inhibitor and penicillin. All of you were correct in one way or another, but magnus receives the coveted Piston Cup Lapel Pin for the first answer.

Moldy Mary's fruit was actually a cantaloupe instead of a grapefruit. The discover was important because it was the first example of a Penicillium that could be grown in suspension culture.
