however, daily output of the 20% biomass loading declined to 17%
from the 10% biomass loading and, finally, it was 2.07 kg. This result
means that a balanced amount of production and ethanol concentration
is very important for high efficiency bioethanol production.
Over all, the ethanol production process from barley straw using
sodium hydroxide pretreatment was effective, and it could be feasible
for commercial bioethanol production in the near future.
