Date:February, 27 2024

Country: United States

Application

• Improved Biomass Conversion: Enhances the efficiency of breaking down biomass into fuels, chemicals, and materials.
• Biomaterial Optimization: Aids in the development of more sustainable and cost-effective bio-based products.

Description

Researchers at the National Renewable Energy Laboratory (NREL) have created the first macromolecular model of the secondary cell wall in Populus wood, detailing the arrangement of cellulose, hemicellulose, and lignin. Using solid-state nuclear magnetic resonance, they gained new insights into lignin's role in biomass recalcitrance. This model aims to improve the deconstruction of biomass for efficient conversion into fuels, chemicals, and materials. The project is funded by the DOE Bioenergy Technologies Office and the Center for Bioenergy Innovation.

 

Pathway Description:

The research used solid-state NMR to analyze the structure of the secondary cell wall in Populus wood. This data defined the arrangement of cellulose, hemicellulose, and lignin. A computer model was created to simulate the macromolecular structure. The model helps improve the efficient deconstruction of biomass for conversion into fuels, chemicals, and materials, focusing on overcoming lignin's resistance.
