В течение 1930-х годов предпринимал

В течение 1930-х годов предпринимались безуспешные попытки улучшить качество пенициллина и других антибиотиков, научившись получать их в достаточно чистом виде. Первые антибиотики напоминали большинство современных противораковых препаратов — было неясно, убьет ли лекарство возбудителя болезни до того, как оно убьет пациента. И только в 1938 году двум ученым Оксфордского университета, Говарду Флори (Howard Florey, 1898-1968) и Эрнсту Чейну (Ernst Chain, 1906-79), удалось выделить чистую форму пенициллина.В связи с большими потребностями в медикаментах во время второй мировой войны массовое производство этого лекарства началось уже в 1943 году. В 1945 года Флемингу, Флори и Чейну за их работу была присуждена Нобелевская премия.
Благодаря пенициллину и другим антибиотикам было спасено бесчисленное количество жизней. Кроме того, пенициллин стал первым лекарством, на примере которого было замечено возникновение устойчивости микробов к антибиотикам.

During the 1930-ies, there have been unsuccessful attempts to improve the quality of penicillin and other antibiotics, learning to get them in a sufficiently pure form. The first antibiotics resembled most of today's anti-cancer drugs — it was unclear whether the medicine kills the pathogen of the disease before it kills the patient. And only in 1938 year two scientists at the University of Oxford, Howard Florey (Howard Florey, 1898-1968) and Ernst Čejnu (Ernst Chain, 1906-79), succeeded in isolating the pure form of penicillin. Due to higher requirements for medical supplies during the second world war, the mass production of this medicine started already in the year 1943. In the year 1945 Flemingu, Flory and Čejnu for their work was awarded the Nobel Prize.Thanks to penicillin and other antibiotics were saved countless lives. Furthermore, penicillin became the first medication, whose emergence was seen example of sustainability of microbes to antibiotics.

During the 1930s, we were made ​​unsuccessful attempts to improve the quality of penicillin and other antibiotics, learning to receive them in a sufficiently pure form. The first antibiotics were like most modern anti-cancer drugs - it was unclear whether the drug would kill the pathogen before it kills the patient. It was only in 1938, two Oxford University scientist Howard Florey (Howard Florey, 1898-1968) and Ernst Chain (Ernst Chain, 1906-79), succeeded in isolating pure form penitsillina.V due to a greater need for medication during the Second World War mass production of the drug began in 1943. In 1945 Fleming, Florey and Cheney was awarded the Nobel Prize for their work.
Countless lives have been saved by penicillin and other antibiotics. Furthermore, Penicillin was the first drug for example which has been observed the occurrence of microbes resistant to antibiotics.
