...discovery of penicillin (almost by accident) in 1928 was a conspicuous breakthrough. Britain's Dr. Alexander Fleming noticed that the mold Penicillium notatum secretes a substance that kills certain bacteria growing on culture dishes. Later it was found that the secretion also kills many disease-producing organisms in the human body. It also does its job without any appreciable damage to human tissues. Fleming's great discovery focused attention on the fact that some micro-organisms are powerful chemical weapons that can be used against other disease-causing microorganisms...
...spite of such failings, gramicidin touched off a chain reaction. Dubos announced its discovery in 1939. A group of British researchers heard about it and recalled Alexander Fleming's Penicillium notatum. The substance it secreted is penicillin. Ripples of excitement spread through the world's biological laboratories...
...blue-green mold, Penicillium notatum, which excretes penicillin, has a laboratory rival. Last week a biochemical team led by Dr. Vincent du Vigneaud of the New York Hospital-Cornell Medical...
...industrial, university and Government researchers have isolated over 200,000 varieties. Useful microbes may turn up anywhere-in the air, on the water, on forest leaf mold, in city garbage cans. A potent industrial bacillus was discovered in the intestines of a grasshopper. The best strain of the mold Penicillium notatum, which makes life-saving penicillin, was first noticed on a cantaloupe rind...
...hope against tuberculosis was reported in Science last week. A green mold believed to be of the penicillium family it attacks the tubercle bacillus. Its discoverers, Drs. David Kimball Miller and Albert Carl Rekate of the University of Buffalo School of Medicine, reported promising results on guinea pigs...
