Screening potential polyhydroxyalkanoate-producing bacteria from wastewater sludge.
Article in Archives of microbiology, 2023. 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
We applied fluorescence staining of Nile red, polymerase chain reaction (PCR), and carbon substrate utilization and pressure tolerance analysis to execute three-stage screening for potential polyhydroxyalkanoate (PHA) producers in the sludge samples of 21 large-scale wastewater treatment plants of city and industrial parks in Taiwan area. Total 35,429 colonies were grown on 196 plates, the screened 30 strains were subjected to 16S rRNA analysis, and 18 identified genera belonged to Proteobacteria (67%), Firmicutes (17%), and Actinomycetota (16%). The PHA accumulation results revealed that nine genera (50% of 18 screened) produced PHAs by limiting the nitrogen source and excess single carbon sources of glucose in an aerobic status. The PHA accumulation percentage was 1.44-58.77% at dry cell weight, and the theoretical yield from glucose was 0.52-58.76%. Our results indicate that our triple-screening method is promising for identifying a high biodiversity of PHA-accumulating bacteria from activated sludge for future industrial applications.
