Means and methods to overrule glucose-mediated repression of respiration in yeast

The present invention relates to the field of biochemistry, particularly to the field of yeast fermentations and yeast biomass production, more particularly to modulation of oxidative respiration in yeast. In this application it is disclosed that increasing the respiratory activity in yeast cells reduces the lag phase when switching said yeast cells from glucose to other nutrients. Additionally, a new mutant yeast allele was found that significantly reduces the lag time. The means and methods described herein solve the problem of microbial growth arrest during industrial fermentations when yeasts have to switch to other nutrient sources and provide solutions for the troublesome yeast biomass production.
