Date of discovery[edit]

The article says "The effect was discovered in 1857 by Louis Pasteur, who showed that aerating yeasted broth causes yeast cell growth to increase, while conversely, fermentation rate decreases."

And, indeed, the site whonamedit gives following references :
L. Pasteur: Mémoire sur la fermentation appellée lactique. Comptes rendus de l’Académie des sciences, Paris, 1857, 45: 913-916; Nouveaux faits pour servir à l'histoire de la levure lactique. Comptes rendus de l’Académie des sciences, Paris, 1859, 48: 337-338.

For the first reference, you can look here : Gallica, site of the French National Library

Well, p. 915, we read : « Ces fermentations doivent s'effectuer de préférence à l'abri de l'air, sans quoi elles sont gênées par des végétations ou des infusoires parasites. » : « It is preferable that these fermentations happen in the absence of air, otherwise these are hampered (inhibited) by parasitical vegetations or infusories. » If I am not wrong, there is nothing closer to the Pasteur effect in this article. Can one really say that Pasteur here describes the Pasteur effect ?

For the second reference, look at : Gallica. Here, I don't see anything that resembles the Pasteur effect.

The German Wikipedia says that Pasteur discovered the Pasteur effect in 1861. Perhaps this is more accurate. See on the French Wikisource a publication of Pasteur in the Bulletin de la Société chimique de Paris (Details here).

Perhaps a reference to the 1861 publication should not be bad. Marvoir (talk) 12:33, 30 December 2007 (UTC)[reply]

Hi Marvoir! It has been 15yrs. since your comment but after spending the day tracking down sources, I strongly agree with your assessment that the Pasteur Effect was first outlined in 1861 and have updated the article accordingly. Thanks for linking to the Wikisource document! BluePenguin18 🐧 ( 💬 ) 22:02, 24 September 2022 (UTC)[reply]
