<P> Some science historians 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 . According to K.L. Manchester , what Béchamp called `` zymase '' was invertase . </P>
