The invention provides compositions and methods for the synergistic degradation of oligosaccharides by endoglucanases. The invention further provides recombinant host cells containing one or more genes encoding endoglucanses which are capable of the synergistic degradation of oligosaccharides. Preferred host cells of the invention are ethanologenic and capable of carrying out simultaneous saccharification and fermentation resulting in the production of ethanol from complex cellulose substrates
