Baker’s yeast, Saccharomyces cerevisiae, is used industrially to produce a great variety of biochemicals. These biochemicals can be produced from waste material from the agricultural or forest industry (second-generation biomass). During the mechanical and enzymatic degradation of biomass acetic acid is released. Acetic acid inhibits the growth and the biochemical production rate of yeast. Now, researchers at Chalmers have used high-resolution CRISPRi library screening to provide a new understanding of the stress response of yeast, and they found new target genes for the bioengineering of efficient industrial yeast.
