The bioethanol for use as a liquid fuel by fermentation of renewable biomass as an alternative to
petroleum is important from the viewpoint of global environmental protection. Recently, many
scientists have attempted to increase the productivity of bioethanol process by developing
specific microorganism as well as optimizing the process conditions. In the present study, which
is based on our previous investigation on the pretreatment process, the productivity of
bioethanol obtained from simultaneous saccharification and fermentation (SSF) process was
compared between various domestic materials including barley, brown rice, corn and sweet
potato. Additionally, Solid- glucoamylase (SGA; developed in Changhae Co.), from modified
strain with UV, was used. The result was compared to commercial glucoamylase. It was
observed that the fermentation rate was increased together with the yield which can be derived
from the final ethanol concentration. Especially, in the case of brown rice, compared to the
experimental results using previous saccharification enzyme, the final ethanol concentration was
1.25 times higher and 12.82% of the yield was increased. Also, the time required for reaching
95% of the maximum ethanol concentration is significantly reduced, which is approximately 36
hours, compared to 88 hours using commercial glucoamylase.
