1 · What the graph read from 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.

2 · The registry

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

Biological ammonium nitrogen removal in tannery wastewater is significantly hindered by hexavalent chromium (Cr(VI)) and high salinity. In this study, Sulfitobacter dubius PT04, a newly isolated, salt-tolerant marine bacterium from deep-sea hydrothermal vent sediment in the South Atlantic Ocean, was characterized for its ability to simultaneously remove total ammonia nitrogen (TAN) and Cr(VI). This strain demonstrated effective removal across a pH range of 6-8, temperatures of 25-35 °C, and salinity levels of 0-6%.Optimal conditions identified using Response Surface Methodology (RSM) were pH 6.92, 27.69 °C, and 3.78% salinity. Most TAN was assimilated into biological nitrogen, effectively reducing inorganic nitrogen pollutants. Additionally, Cr(VI) removal was facilitated by enzymatic reactions with reduction activity predominantly in the cell membrane, followed by extracellular release of Cr(III) with minimal surface adsorption. After 7 days of treatment, strain PT04 achieved removal rates of 90.66% for TAN and 74.81% for Cr(VI), highlighting its bioremediation potential for TAN and Cr(VI) in tannery wastewater.
