microbes that consume the sugars, aside from raw materials, are also influenced by cellulose enzymes used during
the study that already being stored for a while and made the quality of certain enzymes decreased.
Figure 2 would look right if the y axis is the activity of cellulose enzymes. From time to time the performance of the
enzyme will decrease or stop. The longer interaction between the enzymes with substrate the more glucose is
formed. However, at a certain time of hydrolysis glucose concentration will also decrease. This decrease is caused
by the accumulation of the products that have been formed earlier and leading to inhibition of the cellulose enzyme.
Cellulose enzyme inhibitors are glucose and cellobiose. Cellobiose inhibits the exogluconase enzyme whereas
glucose inhibits the ß-glucosidase enzyme (Ambriyanto, 2010).
