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

초록

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 (MDK2023a), 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. (c) 2026 The Author(s).
