Abstract

We demonstrate improved ethanol yield and productivity through cofermentation of cellobiose and galactose by an engineered Saccharomyces cerevisiae strain expressing genes coding for cellodextrin transporter (cdt-1) and intracellular β-glucosidase (gh1-1) from Neurospora crassa. Simultaneous fermentation of cellobiose and galactose can be applied to producing biofuels from hydrolysates of marine plant biomass.
