Flocculation aggregation 違い
WebFlocculation is then used to mean aggregation caused by bridging between particles, usually with long-chain polymers. In this sense, flocculation produces stronger and hence larger aggregates (flocs) than coagulation. Since aggregates have fractal character, and their density decreases with increasing size, those produced by polymers tend to ... 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.

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.
