4. Conclusions
To utilize cassava pulp containing abundant starch and cellulosic
fiber, its components were converted to ethanol using S. cerevisiae
strain K7G displaying glucoamylase on its cell surface, which was
constructed using a cell surface-engineering system based on aagglutinin.
The strain K7G effectively produced high yields of
ethanol from cassava pulp pretreated by hydrothermal reaction
(140 C for 1 h) and then by cellulase to hydrolyze the cellulose in
the pulp.
