Control of sweet potato Fusarium wilt and black rot by endophytic Bacillus velezensis with improved lipopeptide production.
Article in BMC microbiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundSweet potato (Ipomoea batatas) production is threatened by fungal diseases like Fusarium wilt and black rot, causing yield losses. Remedies like fungicides pose environmental and health risks, prompting the need for sustainable biocontrol solutions.
resultsIn this study, an endophytic bacterium strain CMML21-49 isolated from sweet potato roots in Naju-si, Korea exhibited strong in vitro antifungal activity against Fusarium oxysporum, Ceratocystis fimbriata, Sclerotinia sclerotiorum, and Rhizoctonia solani. Based on 16S rRNA and gyrB gene sequencing, the strain CMML21-49 was identified as Bacillus velezensis. Lipopeptides (bacillomycin D, fengycin A, surfactin A) were identified by UPLC-QTOF-MS and these crude lipopeptides drove the antifungal effects, achieving strong inhibition of F. oxysporum and C. fimbriata. Optimized culture conditions yielded 0.93 g/L lipopeptides, scaled to 0.96 g/L in a 1.5 kL fermenter, and a spray-dried formulation maintained high viability (6.4-8.9 × 10
conclusionThis study presents optimized large scale culture conditions for the B. velezensis strain as well as excellent storage stability and suitability for long-term transport and on-farm use. The findings highlight the B. velezensis strain as a promising and sustainable biocontrol agent, offering a scalable, eco-friendly biocontrol solution for sweet potato fungal diseases.
