Table 3 Summary of all hydrolysis experiments after 48 hour of hydrolysis. The total energy input was calculated by integrating the measured power input over the 48 hour hydrolysis. Averaged power inputs where then calculated from the total energy inputs

From: Torque measurements reveal large process differences between materials during high solid enzymatic hydrolysis of pretreated lignocellulose
