title: Molecular tools and protocols for engineering the acid-tolerant yeast Zygosaccharomyces bailii as a potential cell factory.
abstract: Microorganisms offer a tremendous potential as cell factories, and they are indeed used by humans for centuries for biotransformations. Among them, yeasts combine the advantage of unicellular state with a eukaryotic organization, and, in the era of biorefineries, their biodiversity can offer solutions to specific process constraints. Zygosaccharomyces bailii, an ascomycetales budding yeast, is widely known for its peculiar tolerance to various stresses, among which are organic acids. Despite the possibility to apply with this yeast some of the molecular tools and protocols routinely used to manipulate Saccharomyces cerevisiae, adjustments and optimizations are necessary. Here, we describe in detail protocols for transformation, for target gene disruption or gene integration, and for designing episomal expression plasmids helpful for developing and further studying the yeast Z. bailii.
