Complete genome sequence and analysis of a Saccharomyces cerevisiae strain used for sugarcane spirit production.

ABSTRACT: Distillation of fermented sugarcane juice produces both rum and cachaça, significant sources of revenue in Brazil and elsewhere. In this study, we provide a genomic analysis of a Saccharomyces cerevisiae strain isolated from a cachaça distillery in Brazil. We determined the complete genome sequence of a strain with high flocculation capacity, high tolerance to ethanol, osmotic and heat shock stress and high fermentation rates and compared the sequence with that of the reference S288c genome as well as those of two other cachaça strains. Single-nucleotide polymorphism analysis identified alterations in genes involved in nitrogen and organic compound metabolism, integrity of organelles and ion homeostasis. The strain exhibited fragmentation of several flocculation genes relative to the refer
