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’. Particle agglomeration refers to formation of assemblages in a suspension and represents a mechanism leading to the functional destabilization of colloidal systems. During this process, particles dispersed in the liquid phase stick to each other, and spontaneously form irregular particle assemblages, flocs, or agglomerates. This phenomenon is also referred to as coagulation or flocculation and …

WebJan 1, 2014 · Flocculation – process during which particles, for example, of a soil, dispersed in a solution contact and adhere each another, forming clusters, flocks, flakes, or clumps of a larger size.
