YEAST STRAIN OF SACCHAROMYCES CEREVISIAE WITH FUNCTIONAL EXPRESSION OF A GLUT TRANSPORTER

摘要

The invention relates to a yeast strain of Saccharomyces cerevisiae which, due to deletion of the genomic sequences, does not produce any hexose transporters and which as a consequence cannot propagate on substrates that have hexose as the only carbon source. The capability of the strain of propagating on substrates that have hexose as the only carbon source can be re-established by expression of a GLUT4 gene.
