Bead mill or bead beating are shaking vessels filled with quartz or metal (so-called beads), in which microalgae are disrupted by agitation, friction, collision and grinding [42,60]. Therefore, cells are damaged by direct impact with the beads at high speed. The size of beads is important; the higher the volume ratio of beads to cell suspension, the faster the rate of cell disruption [43].
