Bioreduction of hexavalent chromium and removal mechanisms using Staphylococcus succinus.
Article in World journal of microbiology & biotechnology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
The microbial reduction of hexavalent chromium (Cr(VI)), particularly by bacteria, has been extensively studied, revealing varying removal mechanisms among different strains. This investigation identified a novel bacterial strain, Staphylococcus succinus subsp. Succinus AMG-D1, which was isolated from mining soil and Cr(VI)-resistant. This strain demonstrated the capability to completely remove a high concentration of 200 mg/L Cr(VI) within 120 h at pH 7 and 35 °C. Moreover, it effectively reduced repeated contamination of 100 mg/L Cr(VI). Scanning electron microscopy analysis confirmed the strain's high resistance to Cr(VI), coupled with the secretion of a viscous material, possibly metal-adsorbing exopolysaccharides. Energy dispersive X-ray peaks analysis revealed characteristic chromium peaks, indicating the presence of adsorbed Cr(VI) and/or precipitated species of reduced chromium (Cr(III)). Further investigations into Cr(VI) removal mechanisms have revealed a detoxification process involving adsorption, accumulation, and enzymatically mediated biological reduction. This reduction predominantly occurs through constitutive cytoplasmic proteins. Moreover, a protein with a molecular weight of approximately 30 kDa was identified on an SDS-PAGE gel, potentially responsible for Cr(VI) reduction. The remarkable resistance and substantial reduction capabilities of Staphylococcus succinus position it as a promising strain for bioremediation applications.
