Thermal hydropulping permits the selective removal and recovery of hemicellulose (pentosans) from wheat straw (WS). WS was pulped with water at predetermined temperatures in the range of 170.degree.-190.degree. C, 20 or 30 min. After 30 min of thermal hydropulping at 185.degree. C, 94% of the WS pentosans were removed and the residual pulp remained rich in lignin and cellulose. Treatments that disrupt the lignin-hemicellulose-cellulose (LHC) complex prepare biomass for total utilization. The residual pulp and extracted hemicellulose components are promising sources of fermentable sugars for [microbial] alcohol fuel production.
