Photosynthetic accumulation of carbon storage compounds under CO₂ enrichment by the thermophilic cyanobacterium Thermosynechococcus elongatus.
Article in Journal of industrial microbiology & biotechnology, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
The growth characteristics of Thermosynechococcus elongatus on elevated CO₂ were studied in a photobioreactor. Cultures were able to grow on up to 20% CO₂. The maximum productivity and CO₂ fixation rates were 0.09 ± 0.01 and 0.17 ± 0.01 mg ml⁻¹ day⁻¹, respectively, for cultures grown on 20% CO₂. Three major carbon pools--lipids, polyhydroxybutyrates (PHBs), and glycogen--were measured. These carbon stores accounted for 50% of the total biomass carbon in cultures grown on atmospheric CO₂ (no supplemental CO₂), but only accounted for 30% of the total biomass carbon in cultures grown on 5-20% CO₂. Lipid content was approximately 20% (w/w) under all experimental conditions, while PHB content reached 14.5% (w/w) in cultures grown on atmospheric CO₂ and decreased to approximately 2.0% (w/w) at 5-20% CO₂. Glycogen levels did not vary significantly and remained about 1.4% (w/w) under all test conditions. The maximum amount of CO₂ sequestered over the course of the nine-day chemostat experiment was 1.15 g l⁻¹ in cultures grown on 20% CO₂.
