Left monomeric glucose and xylose yields at 72 h of saccharification of ball-milled switchgrass from Fig. 1 compared to the median particle size as a function of the ball milling time. Saccharification was carried out as in Fig. 1. Right monomeric glucose and xylose yields at 72 h of saccharification of ball-milled switchgrass from Fig. 1 compared to the surface area as a function of the ball milling time. Saccharification was carried out as in Fig. 1
