Abstract

The present invention is directed to the construction of prototrophic, cellulo lytic strains of Saccharomyces cerevisiae with tethered and secreted cellulases and selection-based improvement of growth on cellulose by these strains. In some embodiments, host cells of the invention are able to produce ethanol using crystalline cellulose as a sole carbon source.
