Sustainable xylitol production using genetically engineered yeast

Overview

This innovative solution presents a sustainable and low-energy alternative for the production of xylitol, a sugar alcohol used as a sweetener in various food products. Traditionally, xylitol is produced through a chemical process involving high pressures, temperatures, and catalysts, which results in high energy consumption and low selectivity. The proposed method utilizes a genetically engineered yeast strain that transforms xylose into xylitol with nearly 100% yield, high productivity, and without generating other polyols. This biological process is not only eco-friendly but also economically advantageous, offering a more sustainable avenue for xylitol production.

Technical specifications

• Genetically engineered yeast strain: Developed for high-efficiency conversion of xylose into xylitol.
• Virtually 100% yield: The process achieves high selectivity, focusing solely on xylitol production.
• Energy-efficient process: Operates without the need for high temperature and pressure or chemical catalysts.
• Specificity and productivity: No production of other polyols, ensuring high purity of the final product.
• Future validation: Optimization and validation in lab-scale conditions are planned over the next six months.

Technology readiness level

Currently, this technology is at TRL 4, having been validated in laboratory settings. Further development and optimization phases are scheduled, aiming to advance the readiness level for broader application and commercial use.
