Laccase-Mediated Incorporation of Xylans and Lignin-Carbohydrate Complexes into High-Yield Eucalyptus Kraft Fibers.
Article in ACS omega, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Water-soluble products derived from biomass processing hold significant potential to enhance biorefinery viability due to their versatile applications. However, their use in the modification of paper products remains underexplored. Here, corn stover and sugarcane bagasse provided water-soluble products being incorporated into high-yield eucalyptus kraft pulps. The water-soluble products were extracted from ball-milled or alkaline-sulfite pretreated biomass using a xylanase-assisted procedure. Feruloylated arabinoxylans and lignin-carbohydrate complexes (LCCs) predominated in the extracted mixtures. The water-soluble products were incorporated into the fibers using laccase-mediated reactions. The fibers incorporated up to 15.4 g of water-soluble products/100 g of pulp, depending on the biomass source and pretreatment type. The highest incorporation levels were achieved with the water-soluble products recovered from ball-milled sugarcane bagasse. This fraction underwent significant polymerization of feruloylated arabinoxylans during laccase treatment. Paper sheets prepared from fibers with high levels of xylan and LCCs exhibited decreased water contact angles, indicating their potential suitability for a more wettable brown tissue paper. High-resolution X-ray photoelectron spectroscopy revealed an increase in the content of carboxyl and ester groups, corroborating the incorporation of xylans and LCCs into the fibers. The study presents novel strategies for modifying fiber properties through the use of agricultural byproducts.
