Cellulose as a pharmaceutical feedstock

Cellulose is the most abundant biopolymer on Earth. Our novel enzyme cascades and integrated fermentation platforms convert agricultural waste streams into pharmaceutical-grade starting materials and API intermediates with stereochemical precision.

CELLU- LOSE Crop residues Wood pulp ENZYME CASCADE FERMEN- TATION Pharma KSMs API intermediates Chiral building blocks

Glucose liberated from cellulose via engineered cellulase cascades enters purpose-designed fermentation pathways. Our microbial hosts convert these sugars into high-value pharmaceutical precursors with stereochemical control rivalling classical synthetic chemistry.

Key targets include chiral amino acids, hydroxylated organic acids, and nitrogen-containing heterocycles serving as building blocks for active pharmaceutical ingredients. The process integrates seamlessly with existing pharmaceutical supply chains.
