Description

Ya-Jun Liu and co-authors investigate in 2026 why plant material resists being turned into sugars. Factories use cellulase enzymes to break down tough plant fibres, yet compounds in the biomass quietly switch those enzymes off. The study identifies phenolic compounds, especially phenolic aldehydes, as the culprits behind much of that loss.

Experiments showed the phenolics form permanent chemical bonds with enzyme side chains, a process that needs oxygen and links enzyme molecules together until they stop working. Removing oxygen, or adding competing amino compounds, reduced the damage. The phenolics came both from lignin breakdown and from raw plant extractives. For biofuel and biorefining readers, the work gives practical pretreatment guidance: limit leftover phenolics so enzymes keep working longer.
