Biorefinery platform using wild yeast for soybean waste valorization

Overview

This innovative biorefinery platform leverages the metabolic diversity of over 700 wild yeast strains to convert soybean wet gum waste into valuable bio-based ingredients. By harnessing the nutritional properties of phospholipids, glycerol, fatty acids, and sugars in the waste, the platform aims to produce metabolites with high commercial potential. The approach not only addresses waste management but also unlocks new opportunities in food, feed, and bioindustrial markets by developing novel ingredients.

Technical specifications

• Yeast Strain Screening: Utilizes a collection of 700+ wild yeast strains screened for growth on soybean wet gum waste.
• Metabolite Identification: Growth-positive strains are analyzed to produce metabolically valuable compounds, guided by a phenotypic database.
• Fermentation Optimization: Key parameters like C:N ratio, pH, and aeration are optimized to maximize yield.
• Compound Characterization: Involves polysaccharide composition, lipid profiling, and novel metabolite analysis.
• Scalability: Yeast fermentation is scalable and compatible with GRAS standards, facilitating regulatory compliance and commercial scalability.

Technology readiness level

The current technology readiness level is 2, indicating that the concept has been formulated and initial research activities have been conducted. Further validation and optimization are planned to advance the technology towards commercial application.
