Abstract
The invention is directed to non-natural yeast able to secrete significant amounts of glucoamylase into a fermentation media. The glucoamylase can promote degradation of starch material generating glucose for fermentation to a desired bioproduct, such as ethanol. The glucoamylase can be provided in the form of a glucoamylase fusion protein having a S. cerevisiae mating factor alpha 2 (Sc MFα2) or repressible acid phosphatase (Sc PHO5) secretion signal.
