An investigation on lead removal with newly isolated Backusella circina.

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
In this study, the Pb(II) biosorption performance of newly isolated fungal strain, used as a biosorbent, was analyzed. Fungal strain was identified as Backusella circina according to the internal transcribed spacer (ITS) region. Following Pb(II) biosorption, Fourier-transform infrared spectroscopy was performed to compare pristine and Pb(II) biosorped biomass. The effects of pH, fungal biomass amount, temperature, interfering metal ions, initial concentration of Pb(II) and contact time on biosorption performance of B. circina were examined to optimize the biosorption conditions from aqueous solutions. It was observed that optimum Pb(II) biosorption was performed at pH 6.0. Maximum Pb(II) biosorption capacity was found to be 30.69 at 50 mg/L initial concentration of Pb(II) and equilibrium was established after 60 min. It was indicated that the equilibrium data were better fitted to Langmuir isotherm model and it is better to interpret the kinetic data by the pseudo-second-order model. The competitive Pb(II) biosorption capacity was found to be increased in the presence of co-existing metal ions. To the best of knowledge from related literature, Pb(II) biosorption performance of B. circina has not been reported in advance. In conclusion, Pb(II) biosorption performance of B. circina was revealed as an efficient biosorbent in terms of no requirement of modification, ease of preparation and low cost obtainability.
