Implication

Feasibility study demonstrates valorization of sugar beet pulp into bioethanol and pharmaceutical precursors, highlighting sustainable routes for agricultural waste upcycling.

Key Points

To evaluate the technical feasibility of an integrated biorefinery process that fractionates sugar beet pulp into bioethanol, high-value chemicals, and therapeutic intermediates.
Fractionated sugar beet pulp via mild steam explosion into soluble pectin and insoluble cellulose streams.
Hydrolyzed cellulose with cellulases to yield glucose for fermentation into bioethanol using commercial yeast.
Separated pectin-derived arabinose and galacturonic acid via centrifugal partition chromatography or ultrafiltration, followed by biocatalytic conversions using mutant transketolase and transaminase enzymes.
Cellulose hydrolysis yielded glucose that fermented into bioethanol at a high yield.
Biocatalytic conversion of l-arabinose using a mutant transketolase generated l-gluco-heptulose, a compound with therapeutic potential in cancer and hypoglycemia.
Transaminase reactions demonstrated the preliminary capacity to selectively aminate l-gluco-heptulose into a chiral aminopolyol.
