Fig. 3From: Engineering Pichia pastoris with surface-display minicellulosomes for carboxymethyl cellulose hydrolysis and ethanol productionEnzyme activity of minicellulosomes on the cell surface of (a) Y-IM2 or (b) Y-IM3 yeast against Avicel, PASC and CMC at the different ratios of EG, CBH, BGL and CBM. The free cellulases were used as a control. It should be noted that this enzyme activity assay was detected by determination of the reducing sugars within the first 30 minBack to article page
