Clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated (Cas) immune systems in bacteria have been used as tools for genome engineering. Thus far, the CRISPR-Cas system has been used in various yeast, bacterial, and mammalian cells. Saccharomyces cerevisiae is a nonpathogenic yeast, classified under “generally recognized as safe”, and has long been used to produce consumables such as alcohol or bread. Additionally, recombinant cells of S. cerevisiae have been constructed and used to produce various bio-based chemicals. Some types of CRISPR-Cas system for genetic manipulation have been constructed during the early developmental stages of the CRISPR-Cas system and have been mainly used for gene knock-in and knock-out manipulations. Thereafter, these systems have been used for various novel purposes such as metabolic engineering and tolerance engineering. In this review, we have summarized different aspects of the CRISPR-Cas in the yeast S. cerevisiae, from its basic principles to various applications. This review describes the CRISPR system in S. cerevisiae based on the differences in its origin and efficiency followed by its basic applications; for example, its involvement in gene knock-in and knock-out has been outlined. Finally, advanced applications of the CRISPR system in the bioproduction of useful chemicals have been summarized.
