Plasmid-Mediated Biodegradation of Chlorpyrifos and Analysis of Its Metabolic By-Products.
Article in Current microbiology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Organophosphate pesticide persistence is an emerging menace to the environment and despite this fact, its use has been enhanced due to its high efficiency. Bioremediation using microorganisms would be the only means by which these hazardous compounds could be wiped out without disturbing the environmental harmony. The current work studied the molecular mechanism of degradation of Chlorpyrifos (CP) by a bacterial consortium C5 comprising of three soil isolates Staphylococcus warneri (CPI 2), Pseudomonas putida (CPI 9) and Stenotrophomonas maltophilia (CPI 15), which unveiled that the property is plasmid borne. All the isolates were found to possess a 4 kb plasmid which could be cured only by using sodium azide. The Escherichia coli JM109 cells when transformed individually with the plasmid of the isolates showed CP degradation in mineral salts medium (MSM) that contained CP as the sole carbon source. The degradative enzyme organophosphorus hydrolase (~ 60 KDa) of the isolates was extracted and purified to 31.85, 26 and 37.74 fold, respectively. The possible metabolic by-products of CP degradation by the consortium C5, were also analysed. The LC-Q-Tof MS analysis revealed the presence of the major metabolite 3, 5, 6 -trichloropyridine (TCP) with the formation of chlorpyrifos oxon as the intermediate. The isolates also showed trichloropyridine degradation (> 80%) individually in MSM-TCP medium proving its efficiency to remediate both CP and TCP.
