Suitability of Peroxidase-Suppressed Transgenic Hybrid Aspen (Populus sieboldii X Populus gradidentata) for Pulping
Bibliographic record
Abstract
Summary Lignin content, lignin composition and lignin removal were investigated in hybrid aspen ( Populus sieboldii X Populus gradidentata ) with suppressed peroxidase (POX) contents, involved in the dehydrogenative polymerization of monolignols. No significant suppression of the lignin content of the transgenic hybrid aspen was observed, but one (POX 29) of the POX-suppressed hybrid aspen species had a lower lignin content and gave a higher pulp yield at the same lignin content in kraft pulping than the control wild type. The molecular weight distribution of kraft lignins, sugar compositions and yields of nitrobenzene oxidation products of the transgenic woods were not different from those of the wild-type wood. These results indicate that suppression of POX may hold promise for producing woods suited for milder kraft pulping conditions using less chemicals and lower pulping temperature.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
