Pasteur effect in glycolysis

WebThe Pasteur effect is an inhibiting effect of oxygen on the fermentation process. The effect was discovered in 1857 by Louis Pasteur, who showed that aerating yeast broth causes yeast cell growth to increase, while conversely, fermentation rate decreases. Web16 Jun 2024 · The study of the biochemistry of glycolysis started with the experiments of the French scientist Louis Pasteur on yeast in the year 1850. He observed that the consumption of glucose decreased significantly under aerobic conditions as compared to consumption under anaerobic conditions, this effect is known as the Pasteur effect. …
