Summary
Aspen wood was ball milled for times as long as 10 days. The change in wood morphology was examined in the ultraviolet microscope. The accessibility of the milled wood to cellulase was also determined. Soon after the commencement of the milling, part of the wood took on a characteristic appearance in which the cell wall material was completely broken down. The proportion of this disordered wall material (DWM) increased with increased time of milling. The accessibility to cellulase increased with the proportion of DWM produced by the milling.
