Bacillus subtilis spore surface display enhances manganese peroxidase stability and stress resistance.
Article in Bioresources and bioprocessing, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Manganese peroxidase (MnP) is in increasing demand due to its ability to degrade straw lignin and facilitate the conversion of agricultural waste into valuable feed resources. However, free MnP faces limitations in industrial applications owing to high operational costs, poor stability, and poor resistance to environmental stressors. In this study, MnP derived from Irpex lacteus was displayed on the surface of Bacillus subtilis spores using the cotB protein as an anchor molecule. Compared with refolded MnP expressed in E. coli, the spore-displayed MnP exhibited superior acid resistance, with an optimal pH of 3.5 (compared to pH 4.0 for the free enzyme). Additionally, the immobilized enzyme CotB-MnP retained 73.9% of its initial activity after incubation at 30℃ for 1 h incubation. Notably, immobilization eliminated the inhibitory effects of K⁺ and Zn²⁺ ions, which instead promoted the activity of the spore-displayed enzyme. The reusable spores maintained 69% of their initial activity after three consecutive cycles, highlighting their potential for industrial straw feed processing.
