Screening of a xylanase-producing Trichoderma strain and optimization of its enzyme production conditions.
Article in Biotechnology letters, 2026. 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
Xylanases have attracted considerable attention due to their strong potential for industrial use. In this study, a xylanase-producing strain isolated from soil was identified as Trichoderma semiorbis Tsejk8, and the conditions for xylanase production were optimized. Additionally, two xylanase-related genes were cloned, and their functions were analyzed. The optimal conditions for xylanase production included maltose as the carbon source, peptone as the nitrogen source, an optimal pH of 6.0, and an incubation time of 120 h, yielding an enzyme activity of 40.7 U/mL. Following the purification of xylanase via ammonium sulfate precipitation and ion exchange chromatography, four distinct protein bands were observed. Mass spectrometry analysis of these bands identified 14 associated proteins. Bioinformatics analysis revealed that two of these proteins belong to GH3 (Glycoside Hydrolase family 3) β-xylosidase. In summary, the newly isolated strain Tsejk8 exhibits xylanase activity, offering an effective and eco-friendly means of converting biomass into raw materials for industrial applications.
