Disclosed herein is a method of reducing recalcitrance in cellulosic or lignocellulosic materials, the method comprising: contacting, in a mixture, an irradiated first cellulosic or lignocellulosic material having a first level of recalcitrance with one or more compounds comprising one or more naturally occurring, nonradioactive group 5, 6, 7, 8, 9, 10 or 11 elements (preferably Mn, Fe, Co, Ni, Cu or Zn), to produce a second cellulosic or lignocellulosic material having a second level of recalcitrance lower than the first level of recalcitrance. |
