Earlier work had indicated that enzyme-mediated hydrolysis of xylooligomer-rich water-soluble streams (derived from steam pre-treated wheat straw) resulted in the effective production of xylose which was subsequently used to produce bio-glycol. In th

Although selective enzyme treatments have been used to successfully fibrillate chemical pulps, high lignin-containing mechanical pulps have proven to be more recalcitrant. When a bleached chemi-thermomechanical pulp (BCTMP) was sulfonated prior to en

Steam pretreatment conditions that are typically used to enhance wood derived pellet durability are usually less severe than those used to enhance the enzymatic hydrolysis of woody substrates. In the work reported here steam treated softwoods were us
