TL;DR: A whole-cell biocatalyst with the ability to induce synergistic and sequential cellulose-degradation reaction was constructed through codisplay of three types of cellulolytic enzyme on the cell surface of the yeast Saccharomyces cerevisiae, indicating that simultaneous and synergistic saccharification and fermentation of amorphous cellulose to ethanol can be efficiently accomplished.

TL;DR: The construction of a novel cellulose-degrading yeast strain by genetically codisplaying two cellulolytic enzymes on the cell surface of Saccharomyces cerevisiae indicates that efficient simultaneous saccharification and fermentation of cellulose to ethanol are carried out by a recombinant yeast cells displaying cellulolytics enzymes.

TL;DR: Direct and efficient production of ethanol by fermentation from raw corn starch was achieved by using the yeast Saccharomyces cerevisiae codisplaying Rhizopus oryzae glucoamylase and Streptococcus bovis α-amylases by usingThe C-terminal-half region of α-agglutinin and the flocculation functional domain of Flo1p as the respective anchor proteins.

TL;DR: It is demonstrated that the direct conversion of xylan to ethanol is accomplished by the xylan-utilizing S. cerevisiae strain.

TL;DR: Expressing a Pichia stipitis gene encoding a sugar transporter, SUT1, in a xylose-assimilating S. cerevisiae strain increased bothxylose uptake ability and ethanol productivity during xylosedehydrogenase and xylulokinase and glucose uptake ability during glucose fermentation also increased by expressing of Sut1.
