However, these surface-engineered yeast stains, because of the
nature of the parent laboratory strain, cannot produce and accumulate
high concentrations of ethanol at a rapid rate. Therefore, it
is necessary to apply the surface-engineering technology to
a high-ethanol-yielding and ethanol-tolerant industrial strain to
produce a practically useful yeast strain for ethanol production.
This report describes the development of a surface-engineered
yeast strain displaying R. oryzae glucoamylase using an industrial
ethanol-producing yeast, S. cerevisiae Kyokai no. 7, and its
fermentation properties on cassava pulp.
