World War II was a historical turning point not only for the basis of political power and war tactics, but also for drugs and medical advances.
Between andnew medical techniques were developed as a direct response to new weaponry. One of the more profound advances was penicillin, discovered in by Scottish scientist Sir Alexander Fleming.
During the war, the drug helped reduce the overall number of amputations and deaths. Development of the Drug Fleming observed the growth pattern of mold on a staphylococcus culture plate. Specifically he saw that if Pencillium, a genus of fungi, was grown in the appropriate substrate, it would produce an antibiotic substance, which he called penicillin.

Fleming later deduced that penicillin could be used as an antibiotic to treat life-threatening illnesses including meningitis, pneumonia, syphilis and other forms of bacteria.
Even though penicillin was discovered inbefore the war broke out, it took the devastation of the war to force governments to adopt it on a wide-scale basis and to force companies to produce it en masse.
In andBritish and U. Penicillin was so effective that production increased from million units in early to more than billion units per month by the end of the war in Early Clinical Trials InAlbert Alexander became the first patient to be treated with penicillin.
Alexander's nose had been scratched on a rose bush and the infection from that wound spread. Charles Fletcher, a young British doctor, treated Alexander with penicillin in regular doses over four days.
Within 24 hours of the first treatment, Alexander began to heal. Before a complete recovery, however, Alexander died, but the results were strong enough to encourage doctors to continue testing the drug. Results published in August in the medical journal "The Lancet" showed that four of five patients survived their various illnesses after being treated with penicillin.
Similar results were seen in U.
Penicillin and D-Day The majority of penicillin used during the war was produced by drug giant Glaxo. Supplies of penicillin were sent with the troops making the D-day landings in June It was discovered to be particularly effective against gangrene. As a result, the death toll from infected wounds dramatically decreased.
Penicillin was also used to solve a problem that plagued the battlefield: In the Allied Forces, the average wait time was nearly 14 hours. The longer the wait, the higher the probability that the infected area would need amputation.
Administering penicillin to the wounded vastly reduced the chance that the wound could get infected and increased the survival chances in the interim time between the wounding and surgery. Expansions of Penicillin's Use A further problem on the battlefield was septicaemia, or blood poisoning.
Septicaemia could occur if patients were operated on with equipment that had not been properly sterilized or if bacteria was spread from one patient to another within the hospital or surgical unit. Along with the invention of antiseptics by the English surgeon Joseph Lister, penicillin was used in World War II to keep infections from spreading.
By attacking open wounds with penicillin and sterilizing surgeries with antiseptics, army doctors were able to revitalize troops more quickly.Though, with the climbing requirement for penicillin to treat war wounded, eventually British corporations had ramped up production to produce up to 38 million units of the drug by mid, most of which were sent to North Africa to treat wounded British troops.
tential application in production of penicillin from lactose, a fermentable sugar.
Kinetics of immobilized cell fermentation, showed the penicillin yield of ~ g/l, with highest penicillin concentration of ~ mg/l and the high reactor produc-. The commercial production of penicillin and other antibiotics is the most dramatic example of industrial microbiology.
The annual production of bulk penicillin is about In the process of innoculum preparation the pure culture of Penicillium chrysogenum is prepared in adequate amount for production of penicillin.
The primary stock is added in special agar the special agar should provide sporulation of spores the sporulating medium is used to prepare this working stock. Jan 26, · Penicillin was the first naturally occurring antibiotic discovered. It is obtained in a number of forms from Penicillium moulds.
Penicillin is not a single compound but a group of closely related compounds, all with the same basic ring-like structure (a β-lactam) derived from two amino acids (valine and cysteine) via a tripeptide intermediate.
