NEW ETHANOL TOLERANT YEAST STRAIN USEFUL FOR BIOETHANOL PRODUCTION COMPRISES RECOMBINANT MARKER GENE THAT IMPROVES FERMENTATION PERFORMANCE
The present invention relates to industrial yeast strains for bioethanol production that are marked specifically by insertion of the AGT1gene in a stable, well-conserved position in the genome. The resulting strains are organisms obtained by self-cloning. The insertion not only allows rapid and specific detection by PCR directly in ferment or samples of the production strain and of all wild, contaminant Saccharomyces cerevisiae strains, even when present in low amounts, but also improves the fermentation performance of the strain on starch hydrolysates and other maltose and/or maltotriose containing media.
