It is
well known that lignocellulosic materials normally need
severe pretreatment before conversion to ethanol, so these
results are outstanding compared to existing literature. Even
though no amylases were added in the experiment, the
Novozym 188 (Novozymes A/S) enzyme cocktail is known to
hydrolyze starch as well. The results obtained from convertibility
tests of hydrothermal pretreated and ensiled crops
showed following results of glucose yield: 50.9% for clover
grass silage and 54.0% for both maize and rye silage materials.
