Abstract
A haploid laboratory strain and four industrial (baking, brewing, wine, ATCC) strains of Saccharomyces cerevisiae were transformed with the Lipomyces kononenkoae alpha-amylase-encoding gene (LKA1). These transformants displayed significant differences in terms of the level of secretory expression of LKA1 under control of the PGK1 promoter and terminator, as well as their ability to produce and secrete the LKA1-encoded rawstarch-degrading alpha-amylase and to ferment starch. These results demonstrate the importance of the selection of appropriate host strains for yeast development pursuant to starch conversion into commercially important commodities via consolidated bioprocessing.
