Four types of cell-surface-engineered yeast Saccharomyces cerevisiae displaying glucoamylase, namely, systems A, B, C, and D, were constructed to evaluate their performance in direct ethanol fermentation from raw corn starch. Systems A and B were glucoamylase-displaying nonflocculent yeast (YF237) types that secrete α-amylase into the culture medium and codisplay α-amylase on the cell surface, respectively. Systems C and D were flocculent yeast counterparts (YF207) for systems A and B… CONTINUE READING
