Biodegradation potential of used motor oil by mixed bacterial community: optimization, emulsification activity, bioelectrochemical and metagenomics analyses using single chamber microbial fuel cell.

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
backgroundUsed motor oil (UMO) is a dangerous environmental pollutant that needs to be treated effectively. This work introduces a novel approach for producing bioelectricity and UMO biodegradation simultaneously in a single-chamber microbial fuel cell (SCMFC) using native mixed bacterial cultures.
resultsUnder certain conditions (2% oil, 1% peptone, 4% inoculum, 21 days), the optimized bacterial culture degraded UMO by about 80%. Through bioelectrochemical studies, a maximum voltage of 257 mV and a power density of 36.6 mW/m² were demonstrated, showing a strong correlation between UMO removal and electricity generation. Moreover, metagenomic data showed that Firmicutes, particularly Bacillus, dominated the biofilm at roughly 65%. Fourier Transform Infrared (FTIR) and Gas Chromatography-Mass Spectroscopy (GC-MS) verified the breakdown of complex hydrocarbon molecules, highlighting their crucial role in UMO biodegradation and bioenergy production. The effective elimination of UMOs and simultaneous power generation, supported by metagenomic and biochemical tests, showed the microbial activity and hydrocarbon breakdown.
conclusionsThe results suggest SCMFC technology as a sustainable solution for managing petroleum waste while producing renewable energy.
