who coined the term zymase for enzymes in yeast
Zymase Some science historians[3] suggest that Eduard Buchner, in his 1897 work, merely repeated experiments already made by Antoine Béchamp in 1857. This is not the case : what Buchner obtained with yeast zymase, and without yeast cells, was alcoholic fermentation, while Béchamp had explicitly stated that, in absence of yeast cells, and by use of what he, also, called "zymase", he obtained only sugar inversion and no alcoholic fermentation.[4] According to K.L. Manchester,[5] what Béchamp called "zymase" was invertase.
Alexander Fleming Sir Alexander Fleming FRS FRSE FRCS[1] (6 August 1881 – 11 March 1955) was a Scottish physician, biologist, pharmacologist and botanist. His best-known discoveries are the enzyme lysozyme in 1923 and the world's first antibiotic substance benzylpenicillin (Penicillin G) from the mould Penicillium notatum in 1928, for which he shared the Nobel Prize in Physiology or Medicine in 1945 with Howard Florey and Ernst Boris Chain.[3][4][5] He wrote many articles on bacteriology, immunology, and chemotherapy.
