The theory of the beer fermentation process experienced a long development, in the 19th century, from the mechanical interpretation through the explanation on the basis of simply chemical reactions down to the understanding of the biological anaerobic process of fermentation with participation of brewery yeast and to the importance of enzyme reactions. Then, the measures were followed by isolation and introduction of pure yeast cultures in the production process in breweries and by findings regarding infectious microorganisms in the brewing process. In the nineteen fifties, the cognition of...
