Investigating anaerobic digestion microbiome resilience to high PFOA and PFOS mixtures during cometabolism.
Article in Bioresource technology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Anaerobic digestion (AD) is a reducing environment with high microbial diversity and potential for biotransformation of PFAS. Yet, their fate and impact on the microbial community remains poorly understood. This study evaluated the long-term impact (100 d) of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) spiked at10 mg/L (low) and 100 mg/L (high), respectively. Although resilient to complete system failure, high PFAS concentrations disrupted AD, evidenced by 25-50 % reduction in methane content, 45 -48 % reduction in cumulative biogas production, and accumulation of butyric acid. No significant decrease in PFAS concentration was observed in the liquid fraction after 100 d relative to the kill controls, indicating PFAS adsorption behavior. However, PFAS concentrations were temporally variable. Microbial community analysis revealed enrichment of notable AD groups, such as Firmicutes, Synergistetes, and Methanomassillicoccus phyla in high PFAS reactors, which underscores the potential for the microbiome adaptation and informs future strategies for PFAS-contaminated sludge treatment.
