Fermentation as conceived by Mendel's teacher F. Diebel in his textbook from 1835

This study presents the fermentation process and seed germination in the approach of F. Diebel, Mendel's teacher at Brno Philosophical Institute, in his textbook "Abhandlungen uber die allgemeine und besondere Naturgeschichte, Brunn", published in 1835. This explanation coming from the days before Pasteur's discovery of yeasts brings a lot of simplifications reflecting the time of the textbook origin. These are characterized in notes added to Diebel's explanation.
