Figure 1

Illustration of the selection of optimal combination of yeasts displaying EG with mutated CBM from the yeast mixture displaying 3 cellulases including EG with comprehensively mutated CBM. The yeast mixture consists of yeasts codisplaying 3 cellulases: EG with comprehensively mutated CBM, CBH, and BG. The optimal combination of yeasts displaying EG with mutated CBM for the degradation of the biomass was selected in a medium that contained biomass cellulose as the only carbon source. CBM: Carbohydrate-Binding Module, CD: Catalytic Domain. The optimal combination of yeasts displaying EG with mutated CBM, CBH, and BG could survive because the yeasts could efficiently degrade cellulose and produce glucose.
