Bacillus thermoamylovorans-Related Strain Isolated from High Temperature Sites as Potential Producers of Medium-Chain-Length Polyhydroxyalkanoate (mcl-PHA).
Article in Current microbiology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Thermotolerant bacteria producing medium-chain-length polyhydroxyalkanoate (mcl-PHA) were isolated from various thermal sites, including palm oil mill effluent, textile wastewater, and hot spring water, in Thailand. Fifteen strains were isolated at 45 °C using nutrient-rich (NR) medium. However, only six isolates produced mcl-PHA at 0.41 ± 0.01 g/L to 0.80 ± 0.01 g/L, representing a mcl-PHA content of 29.44% to 50.77% of the dry cell weight (DCW). The six strains of bacterial isolates could utilise a variety of substrates; all were identified as Bacillus thermoamylovorans. The highest mcl-PHA content (50.77% of the DCW) was accumulated by the B. thermoamylovorans strain PHA005 isolated from palm oil mill effluent. The mcl-PHA from strain PHA005 was composed of five different monomers, 3-hydroxyoctanoate (3HO), 3-hydroxydecanoate (3HD), 3-hydroxytetradecanoate (3HTD), 3-hydroxyhexadecanoic acid (3HHD), and 3-hydroxyoctadecanoic (3HOD), with a monomer content of 24.12, 15.50, 13.00, 39.25, and 8.13 mol%, respectively. The optimum temperature for B. thermoamylovorans strain PHA005 growth is 45 °C, and it can survive at up to 60 °C. This is a first report of PHA synthesis by a thermotolerant B. thermoamylovorans. Moreover, the high content of 3HHD monomers (39.25 mol%) has never been reported in Bacillus.
