Question

how did pasteur help the manufacturers of lille and what did he discover about yeast​

Answer 1

Pasteur gave lectures in Lille on fermentation. The chief industry in Lille was the manufacture of alcohol from beetroot, which would go wrong in a short time. Pasteur conducted experiments in their breweries. He helped a manufacturer whose beer was turning out badly, by discovering about yeast. When yeast was used to manufacture beer it stayed good for a long time. Thus Pasteur proved himself useful to the manufacturers of Lille.
