This study investigated the high-efficient process for bioethanol from
barley by various condition. First, higher concentrations of ethanol could be produced
without loss of yield by using reducing water consumption. This is because
it could prevent to increase viscosity despite reducing water consumption.
Second, the ethanol yield could be improved by using reducing particle size of biomass
(increase of enzyme reactive surface). Third, The addition of protease
could have a considerable effect on yield of fermentation, which provides nutrients
to the yeast. This results showed that bioethanol production would provide
efficient ethanol production and lower production costs.
