Hydrogen excess drives metabolic reprogramming and viral dynamics in syngas-converting microbiomes.
Article in Environmental science and ecotechnology, 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
Microbial communities drive essential bioprocesses, including the conversion of synthesis gas into biomethane, a sustainable energy source that supports circular carbon economies. In anaerobic environments, specialized consortia of bacteria and archaea facilitate syngas methanation through syntrophic interactions, where hydrogenotrophic methanogens play a central role in reducing carbon dioxide and monoxide with hydrogen. However, imbalances in gas ratios, particularly excess hydrogen, can disrupt these interactions and impair overall efficiency. Yet, the molecular mechanisms underlying microbial responses to such imbalances remain poorly understood. Here we show that hydrogen excess triggers profound metabolic and viral remodeling in a thermophilic anaerobic microbiome, leading to reduced methane yields and ecological instability. This reprogramming involves transcriptional downregulation of methanogenesis genes in the dominant archaeon
