Summary

Aqueous pretreatment of biomass involves mixing lignocellulosic material with water and heating the resulting slurry under pressure. This pretreatment approach has been called liquid hot water, controlled pH, autohydrolysis, uncatalyzed hydrothermal pretreatment, or variations on these themes. Several technological applications of this approach are under commercial development and are briefly mentioned in this chapter. The focus of this chapter is on the fundamental chemical and physical changes that occur during aqueous pretreatment and how these changes affect the ability of enzymes to hydrolyze plant cell-wall polysaccharides into fermentable sugars. Summaries of the effect of aqueous pretreatment on various lignocellulosic feedstocks are also given.
