抗生素的问世——青霉素的发现巴斯德在青霉素发现前50年已提出微生物之间有抗生(antibiosis)和共生(symbiosis)的关系。1982年意大利的Gosio说青霉菌含抗菌性物质,其后有材料记载从烟曲霉菌得到的物质曾试用于结核治疗,1911年Dubos发现Thyrothricin等虽然都在青霉素发现之前,但当时一般认为由微生物得到的物质毒性强。1928年9月夏天,费莱明在牛津研究室发现了平皿上生长的青霉菌产生的青霉素,这堪称为20世纪的人类遗产。
The advent of antibiotics - the discovery of penicillin Pasteur 50 years before the discovery of penicillin has been proposed microbial antibiotic (antibiosis) and symbiosis relationship. In 1982, Gosio of Italy said that penicillium contained antibacterial substances. Later materials were recorded that substances obtained from Aspergillus fumigatus had been tested for tuberculosis. In 1911 Dubos found that although Thyrothricin and others were all found before penicillin was found, it was generally believed that microbes The resulting material is highly toxic. In the summer of September 1928, Fleming found penicillin produced by penicillium grown on a plate in the Oxford Laboratory, which is called the 20th century heritage of mankind.
