London, November 21 (Xinhua) ' The reporter is yellow) The penicillin that British scientist Alexander and Fleming found has saved the life of countless people, but British researchers have found recently, the fungi which produces penicillin that Fleming found at first are not the kind that people think for a long time, it has been called for more than 80 years by mistake. Fleming found in 1928, the material that a kind of fungi were secreted could kill bacteria when St. Marie medical college works in London, this kind of material is penicillin used extensively later. Hereafter, scientific circles found " produced yellow blue and green mould " that can produce penicillin ,And been thinking all the time this is the bacterium that Fleming found at first. St. Marie medical college has kept Fleming's fungi sample, after this school incorporates into British kingdom Institute of Technology, these samples have been kept all the time too. Kingdom Institute of Technology releases the communique and says, the researchers of this school carried on genetic analysis to these samples on the 21st, find it is not standard " Produce yellow blue and green mould " ,But with a very close bacterium of it, because has not noticed before this, this bacterium has not been named yet. Researcher ask counterpart of all parts of the world offer locality collect reach, produce the yellow blue and green mould sample, find, though they are considered to be a species for a long time through genetic analysis, but " produce yellow blue and green mould " Name have 4 pieces is different species,there are getting more similar very on they, if does not use means genetic not to distinguish difficultly out. Each of Daniel participating in studying says, it means Fleming is very lucky, he not only find can produce fungi of penicillin one, whom other researcher's follow-up isolated but also just the bacterium with same function, it runs into other bacteriums to be but unable to repeat experimental result, have other people perhaps so report find penicillin among other researches. He still shows, this discovery has very strong bio-diversity to explain this kind of fungi, this is a good news for developing new medicine, can explore " relative " of the penicillin Whether can produce the new medical material. The relevant research report has already been published on the academic publication " member's ecology ".
