Abstract
Ferulic acid (3-methoxy-4-hydroxycinnamic acid), present in complex plant cell walls, is covalently cross-linked to polysaccharides by ester bonds and to components of lignin mainly by ether bonds. Ferulic acid has also been shown to occur in dimer- and trimerized forms through oxidative coupling between esterified and/or etherified ferulic acid residues. These cross-links are among the factors most inhibitory to digestion of complex plant cell walls in ruminants. Recently obtained information on ferulic acid and ferulic acid esterases in relation to complex plant cell wall biodegradation is reviewed. A focus of the review is on structural characteristics of plant cell walls associated with ferulic acid, physicochemical properties of ferulic acid esterase and synergistic interaction between ferulic acid esterase and other accessary cell wall degrading enzymes on the release of ferulic acid and plant cell wall biodegradation. Key words: Ferulic acid, hydroxycinnamic acid, feruloyl esterase, interaction effects, polysaccharide, feruloyl-polysaccharides, plant cell walls, biodegradation

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
