Draft genome sequence data of the osmotolerant yeast Starmerella magnoliae JH110 isolated from a honeycomb

Erythritol is a sugar alcohol used as a sweetener in the food industry and is primarily produced through the fermentation of osmotolerant yeasts and fungi. In this study, we analyzed the genome of Starmerella magnoliae JH110 (MDK-2023a), an osmotolerant yeast isolated from a honeycomb and known for producing erythritol. The genome of JH110 was sequenced using the PacBio RS II platform and assembled into four contigs with a total length of 10,358,530 bp and a GC content of 58.5%. Gene prediction was carried out using the MAKER pipeline, and genes for glyoxalase 1 ( GLO1 ), transketolase 1 ( TKL1 ), and erythrose reductase ( ER ) were identified on the same contig. Phylogenetic analyses based on ITS, BUSCO-derived single-copy core genes, as well as GLO1 and TKL1 genes, confirmed that JH110 clustered with other S. magnoliae strains, forming a distinct branch separate from other yeasts. This dataset provides genomic information on S. magnoliae JH110. It is a valuable resource for comparing the genomes of osmotolerant yeasts, studying sugar alcohol biosynthesis, and exploring potential industrial applications.
