Ethanol and biomass production from whey lactose by an engineered Saccharomyces cerevisiae strain


, : Ethanol and biomass production from whey lactose by an engineered Saccharomyces cerevisiae strain. Mededlingen van de Faculteit Landbouwwetenschappen, Rijksuniversiteit Gent 56(4a): 1713-1722

The purpose of this study was to convert a whey/lactose mixture directly to biomass and ethanol by utilizing characteristic properties of the budding yeast Saccharomyces cerevisiae observed during previous studies by the same research group on the production of intracellular beta -galactosidase under the control of the strong inducible GAL promoter. The over-expression of the transcriptional activator GAL4 induces the lysis of the oldest (mother) cells.

The lactose in cheese whey is an interesting substrate for the production of bulk commodities such as bio-ethanol, due to the large amounts of whey surplus generated globally. In this work, we studied the performance of a recombinant Saccharomyces...
