Addition of vegetable oil to enhance the biosynthesis of butenyl-spinosyn in a high production strain Saccharopolyspora pogona.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Butenyl-spinosyn discovered from Saccharopolyspora pogona, is a broad-spectrum bioinsecticide. In order to further improve the production, the fermentation medium of a high-production strain Sa. pogona ASAGF30A11 obtained by mutagenesis, was optimized by adding different species and concentrations vegetable oil. In our study, the effect of peanut oil on the growth and production was proved by monitoring the growth curves, key gene transcription level and content of acyl-CoA. After adding 10 g/L of peanut oil, the additional carbon sources redirected the carbon flux toward strain growth, inhibiting the synthesis of butenyl-spinosyn, while increasing biomass by approximately 1.5-fold. However, when adding 1 g/L of peanut oil, it functions as a surfactant, greatly promoting the synthesis of butenyl-spinosyn, resulting in a 1.52-fold increase in production. The research provides a promising strategy to improve butenyl-spinosyn production.
