Summary

Effects to ethanol: Storing with additives increased the yield of sugars in enzymatic hydrolysis. Water soluble sugars well preserved. Some cellulose hydrolysed during ensiling. Storing altered the structure of the substrate?
Suffered from acid formation when no additives were supplied.
Effects to methane: Storing with or without additives increased methane yield. Formed acids were utilized, as well as the preserved water soluble sugars.
Prolonged storing seemed to decrease methane yields.
