Article Abstract
Erythritol is a natural sweetener produced by microorganisms as an osmoprotectant. It belongs to the group of polyols and it can be utilized by the oleaginous yeast . Despite the recent identification of the transcription factor of erythritol utilization (), the metabolic pathway of erythritol catabolism remains unknown. In this study we identified a new gene, , involved in erythritol assimilation. analysis showed that is a putative isomerase and it is localized in the same region as . qRT-PCR analysis of showed a significant increase in g expression during growth on erythritol and after overexpression of . Moreover, the deletion strain showed significantly impaired erythritol assimilation, whereas synthesis of erythritol remained unchanged. The results showed that is involved in erythritol assimilation; thus we named the gene . Moreover, we suggest the metabolic pathway of erythritol assimilation in yeast .

Xylose is the major pentose and the second most abundant sugar in the lignocellulosic feedstock. Metabolic engineering approaches have been employed to enhance the utilization rate of xylose in yeast. We previously modified Trichosporonoides oedocephalis ATCC 16958 and produced sugar alcohols, including xylitol and erythritol.

Methanol, which is non-food competing, abundant, inexpensive, and potentially renewable, serves as an ideal alternative feedstock for biomanufacturing. Although engineered methylotrophic yeasts have successfully achieved gram-scale production of C2 (acetyl-CoA), C3 (pyruvate), and C6 (fructose-6-phosphate) building blocks from methanol, the production of C4-based (i.e.
