ingnoceklosic materials such as agricultural residues are abundant renewable resources
for the production of sugars which by biotechnological conversion of the hidrolysates
can yield food, liquid tkel and chemicals (Fox et al., 1987, Parekh et al., 1987).The
saccharification is performed in media catalyzed by acids or enzymes. The acid catalyzed
hydrolysis falls into two classes: low temperature concentrated acid processes or high
temperature dilute acid processes. Depending on operational conditions and nature of
