Chain. Ernst Boris

Unfortunately, lysozyme failed to destroy bacteria that caused human diseases and was never used as a medicine. Despite the limited utility of lysozyme, Howard Florey and Ernst Boris Chain of Oxford University later determined both its structure and the mechanism by which it destroys bacteria. These two scientists would figure prominendy in Fleming s greatest discovery penicillin.

According to Macfarlane (1985), there is also controversy about Alexander Fleming s prominence, when most of the work in developing penicillin was done by Howard Horey, assisted by Ernst Boris Chain. Reviewing this controversy, Fleming admittedly discovered penicilhn in 1928 and dnly reported its action (which may have been erroneous), but let the subject lie dormant for the next 12 years. (Penicillin... 

Only towards the end ofthe 1930s, the Australian-bom pathologist Howard W. Florey and the German-Jewish chemist Ernst Boris Chain in Oxford purified peniciUin from fungal cultures. Theyprepared the compound in sufficient quantities to treat for the first time humans. During the war, the experimental conditions were conceivably bad. In order to obtain peniciUin, use was made of urine bottles, bedpans and biscuit tins (Fig. 5.25). The compound was so scarce, that the urine of already-treated patients was worked up in order to recover and recycle the excreted peniciUin. 

Sir Alexander Fleming (1881-1955) received the 1945 Nobel Prize for Medicine along with Sir Howard Walter Florey (1898-1968) and Sir Ernst Boris Chain (1906-1979). 

Step by testing the antibacterial effect of penicillin in humans. Ernst Boris Chain (1906-1979) solved the problem of large scale production of the compound. Penicillin proved its benefit in World War 11, by facilitating the prevention of bacterial infections among Allied troops. Before the 1940s, wound infections caused mat r more fatalities in wars than the wounds themselves. Fleming, Florey and Chain were awarded the 1945 Nobel Prize in physiology or medicine. 

Penicillin Sir Howard Walter Florey and Ernst Boris Chain isolate and purify penicillin. They are awarded, with Sir Alexander Fleming, the 1945 Nobel Prize in Physiology or Medicine. 

Chain, Sir Ernst Boris (1906-79) German-born British biochemist of Russian extraction who isolated and purified penicillin and turned Alexander Fleming s discovery of the antibiotic into one of the greatest successes in the history of medicine. Chain, Howard Florey, and Fleming shared the 1945 Nobel Prize in physiology or medicine. 

The industrial microbial production of penicillin became a reality after the technological breakthrough of submerged (also referred to as deep ) fermentation methods at United States Department of Agriculture s Northern Regional Research Laboratories (NRRL) in Peoria, IL. With the world at war in 1941, Oxford researchers led by Drs Horey, Ernst Boris Chain and Norman Heatley collaborated with NRRL to produce the quantities of penicillin needed for clinical trials. In 1945 Fleming, Florey and Chain were awarded the Nobel Prize in Medicine or Physiology for the discovery of penicillin and its curative effect in various infectious diseases ... 

Twelve years later, the overwhelming casualties on the battlefield during the Second World War led two medical researchers, Howard Florey (1898-1968) and Boris Ernst Chain (1906-1979), to look into resurrecting Fleming s work with penicillin. After much refinement they were able to develop a powdered form of penicillin and experimented with mice. In 1941 the first human was successfully treated. Before long, penicillin was in full production. Fleming, Florey and Chain were awarded the Nobel Prize for Medicine in 1945. ...
