The present invention relates to methods of producing a cellulosic material reduced in a redox active metal cation having a redox potential (E
o
) in the range of about −0.4 to about 1.2 volts, comprising treating the cellulosic material with an effective amount of a chelator to reduce the inhibitory effect of the redox active metal cation on enzymatically degrading or converting the cellulosic material and alternatively also treating the cellulosic material with an effective amount of an oxidant when the redox active metal cation has a low valence state to convert the redox active metal cation to a high valence state to preferentially chelate the redox active metal cation. The present invention also relates to methods for degrading or converting a cellulosic material and to methods of producing a fermentation product.
