- Reasons why he was important
- Florey and Chain
- In the 1930s became interested in Flemings report and so they decided to put a research team together and with government funding they would be able to purify and extract it
- Used the recent freeze drying method to extract pure penicillin
- Tested it on mice first and the tested mice survived from the streptococci bacteria
- Tested it on a human, but the patient died due to a lack of penicillin
- Factors that helped
- Previous knowledge - F+C used Flemings knowledge
- War - countries were more inclined to develop penicillin as they were desperate
- Research teams - large French research team
- Government funding - US government gave $80 million to 4 drug companies
- Industry - mass produced penicillin
- Key individuals
- Technology - freeze drying technology used to refine penicillin
- Alexander Fleming
