Undefined References

The article contains plenty of references in the text, which are not listed in the reference list. For example, (Calleja, 1987), (Stratford and Assinder, 1991), (Masy et al., 1992; Dengis and Rouxhet, 1997), and many more. Would somebody be so kind to fix this?

Article looks like a cut-and-paste job. The reader needs to be told about the basics, particularly in relation to beer brewing.08:23, 24 March 2014 (UTC) — Preceding unsigned comment added by 220.244.89.172 (talk)

Yeast to large for Brownian motion - false statement.

Brownian motion was first describe based on random motion of pollen, a plant cell, suspended in water. On average, most pollen cells are larger than any yeast cell. Thus thew statement that Brownian motion is not applicable to yeast due to size is incorrect. I suspect that the surface charge repulsion plays has a greater influence in inhibiting the flocculation of yeast cells. Noone mentions that cells dying release all kinds of sticky stuff, proteins, lipids and especially DNA, which would cause the cells to stick together. So please correct that statement. — Preceding unsigned comment added by 73.24.230.250 (talk) 04:52, 22 July 2016 (UTC)[reply]

Colloids are generally assumed to be below 1 micron and thus subject to brownian motion. Yeasts are 5-7 microns right on the edge. Take a look down a microscope do you see the motion Brown saw??? No!

The reference to dying cells is irrelevant live cells floc look up the brewing literature! 156.34.18.35 (talk) 15:02, 11 May 2024 (UTC)[reply]
