Increment in anaerobic hydrocarbon degradation activity of Halic Bay sediments via nutrient amendment.
Article in Microbial ecology, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
In this study, hydrocarbon (HC) degradation activity of a HC-rich marine sediment was assessed in anaerobic microcosms during a 224 days incubation period. Natural TOC/N/P ratio of the sediment porewater (1,000/5/1) was gradually decreased to 1,000/40/6 which resulted in approximately ninefold increase in gas production (CH(4)+CO(2)) and HC removal. Addition of external HCs to the microcosms was also resulted in approximately twofold higher gas production and HC removal. A high proportion (92%) of aromatic HCs and all n-alkanes were removed from the microcosms under unlimited nutrient supply conditions without external HC addition. The microorganisms of the sediment degraded a wide range of aliphatic (n-C(9-31) alkanes and acyclic isoprenoids) and aromatic (18 different one- to five-ring aromatics) HCs. Monitoring functional gene and transcript abundances revealed that methanogenesis and dissimilatory sulfate reduction took place simultaneously during the first 126 days, afterwards, only the syntrophic methanogenic consortium was active. Genes and transcripts related to initial activation of HCs were highly abundant throughout the incubation period showing that fumarate addition was the main pathway of anaerobic HC degradation. In conclusion, biostimulation of highly polluted anoxic marine sediments via nutrient amendment is effective and may constitute a suitable and cost-effective field-scale bioremediation strategy.
