WebIn brewing, flocculation involves aggregation of dispersed cells into flocs, and occurs towards the end of fermentation. It is characteristic of stationary-phase or late experimental-phase cells of some strains of yeast ( Mill, 1964 ). Both the genotype of cells and fermentation conditions affect flocculation.

WebSpecifically, flocculation, as it applies to brewer's yeast, is “the phenomenon wherein yeast cells adhere in clumps and either sediment from the medium in which they are suspended or rise to the medium's surface.” This definition excludes other forms of aggregation, particularly that of ‘clumpy-growth’ and ‘chain formation’. WebFeb 9, 2013 · Yeasts can display four types of cellular aggregation: sexual, flocculation, biofilm formation, and filamentous growth. These cell aggregations arise, in some yeast strains, as a response to environmental or physiological changes. Sexual aggregation is part of the yeast mating process, representing the first step of meiotic recombination. …
