The yeast hypoxic responses, resources for new biotechnological opportunities
- 596 Downloads
Recent advances in the knowledge of molecular mechanisms that control the adaptation to low oxygen levels in yeast and their biotechnological applications, including bioproduct synthesis, such as ethanol, glutathione or recombinant proteins, as well as pathogenic virulence, are reviewed. Possible pathways and target genes, which might be of particular interest for the improvement of biotechnological applications, are evaluated.
