The mouldy dish is historical and worth 11,400 pounds

LONDON -- A tiny specimen of penicillin from Alexander Fleming’s laboratory sold for £11,400 at Sotheby’s in London.

The culture was mounted in a glass dish just under two inches in diameter. On the back of the case was written: “The mould which makes penicillin. A. Fleming, 1948.”

Sir Alexander Fleming discovered the germ-killing properties of Penicillium notatum in 1928, but it was not put into general use until 1940.

It was mass-produced during the Second World War, and Sir Alexander, with Ernst Chain and Howard Florey, received the Nobel Prize for Medicine in 1945.
