Assessing the efficiency and the side effects of atrazine-degrading biocomposites amended to atrazine-contaminated soil.

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
Even decades after being banned in Europe, atrazine and its main metabolites can still be found in soils. While bioaugmentation using pesticide-degrading bacteria is already employed for remediating polluted soils, there is a need to improve its efficiency. Investigating the use of carrier materials to deliver pesticide-degrading microorganisms in situ emerges as a promising approach. Here, we generated atrazine-degrading biocomposites by cultivating either a bacterial strain or a four-species consortium on zeolite as the carrier material. Using a microcosm approach, we evaluated their efficiency to mineralize 14C-atrazine in soil compared to free-living cells, and assessed their side effects on the native soil bacterial community using 16S rRNA metabarcoding. We showed that, right after inoculation, atrazine mineralization potential of the free-living cells was higher than that of the biocomposites. However, microcosms inoculated with the biocomposites displayed significantly higher atrazine mineralization potential after 15 and 45 days of incubation, indicating a higher efficiency but also a better stability in soil. Inoculation of free-living cells and biocomposites differently influenced the diversity and composition of the native microbial community, their impacts being modulated by the atrazine contamination scenario. Altogether, our results provide a thorough evaluation of the efficiency and the ecological impact of atrazine-degrading biocomposites in soil.
