Genomic and functional characterization of a lipopeptide-producing endophytic Bacillus velezensis EL isolated from Euphorbia cyparissias L.

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
backgroundLipopeptides, are emerging as sustainable alternatives to synthetic surfactants due to their biodegradability, low toxicity, and broad application in bioremediation, agriculture, and medicine. Endophytic microorganisms, especially those adapted to degraded environments, represent a valuable and underexplored reservoir of such bioactive compounds. Euphorbia cyparissias L., known as pine spurge, is a perennial herbaceous plant from the Euphorbiaceae family, and is highly resistant to environmental stresses, which may result from the presence of specialist endophytic microorganisms that support its adaptation.
resultsA novel endophytic strain, Bacillus velezensis EL, was isolated from surface-sterilized tissues of Euphorbia cyparissias L., a hardy plant growing in degraded soil. Preliminary screening revealed its high biosurfactant activity, including emulsification, oil dispersion, and surface tension reduction. Whole-genome sequencing and functional annotation identified thirteen biosynthetic gene clusters, including nonribosomal peptide synthetase pathways responsible for lipopeptide production. Fourier-transform infrared spectroscopy confirmed characteristic functional groups of lipopeptides, while ultra-performance liquid chromatography–mass spectrometry validated the presence of surfactin and bacillomycin homologs. Process optimization using the Taguchi design significantly enhanced production, yielding 3.841 g/L of crude biosurfactant under optimal conditions. The product exhibited strong surface activity, with high emulsifying and oil displacement performance, and favorable biochemical composition with high protein content.
conclusionsThis study highlights Bacillus velezensis EL as a promising producer of lipopeptide biosurfactants. It also identifies Euphorbia cyparissias L. as a novel and ecologically significant host plant harboring endophytes with industrial biotechnological potential. These findings support further development of endophyte-based systems for sustainable biosurfactant production.
