1 · What the graph read from it

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.

2 · The registry

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

Microorganisms are promising, cost-effective, and sustainable producers of bioproducts, including polyhydroxybutyrate (PHB), a biodegradable polymer that offers an eco-friendly alternative to synthetic plastics. This study investigates PHB production using the newly isolated Vreelandella piezotolerans with orange peel waste as the substrate. Notably, this is the first research to optimize PHA production with V. piezotolerans, utilizing Design Expert 7.0 software. Various bacterial isolates were screened, and the most efficient strain, MH46, was identified as V. piezotolerans through 16 S rRNA sequencing and registered in GenBank (accession number PP826285). Single-factor optimization was conducted to determine optimal fermentation conditions. The results of the single-factor optimization were used to conduct Plackett-Burman design experiments. The response surface optimization was then completed. Results revealed that temperature, agitation rate, and inoculum size significantly influence PHA production. The extracted PHB was characterized using GC-MS, NMR, FTIR, XRD, and thermal analysis. This study is the first to report PHB accumulation by V. piezotolerans using orange peel waste as the sole carbon source.
