Thermal degradation of hemicellulose and cellulose in ball ...
Ball milling is a commonly used method for pretreating wood and other lignocellulosic biomass to improve enzyme reactivity [7,8,9,10] and to separate lignin [11,12,13,14]. This process is also known to reduce the crystallinity of cellulose [ 15, 16, 17 ] and cleave the lignin β-ether linkages [ 12, 14 ], i.e., the dominant type of linkage.
Different Pretreatment Methods of Lignocellulosic …
For pretreatment of biomass, ball milling is an expensive option in terms of energy consumption, which is a huge disadvantage at industrial scale. Also, incapability of milling for removing lignin makes it a less suitable option as enzyme accessibility to the substrate is reduced in the presence of lignin.
