Exploring the mechanisms of supplemented CO
Review in Bioengineered, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 sustainable technology that converts organic waste into renewable energy while reducing greenhouse gas emissions. Recent studies suggest that adding CO₂ to the AD process can improve methane production through different mechanisms. This review examines four key ways CO₂ supplementation can enhance methane yield: (1) direct conversion of CO₂ into acetate by homoacetogens, (2) direct methanation of CO₂ by hydrogenotrophic methanogens, (3) improved breakdown of organic material due to higher enzyme activity, and (4) better digester conditions through pH regulation and reduced ammonia toxicity. By analyzing microbial interactions and process improvements, this paper highlights knowledge gaps and the need for further research to optimize CO₂ addition in different operational settings. These findings are expected to contribute to the development of cost-effective and efficient AD systems that support energy recovery and environmental sustainability.
