Application of intermittent ball milling to enzymatic

2021-2-1  Continuous ball milling might be useful in relocating the enzymes without fully hydrolyzing the accessible lanes. It is thus suggested that the ball milling process could help enzyme loading onto accessible lanes for hydrolysis, while static incubation may be more effective for those loaded enzymes to effectively hydrolyze their accessible lanes of cellulose.
