Genomic and Antifungal Characterization of 36 Bacillus Strains Against Fusarium

A 2026 study by Rim Touati characterizes 36 bacterial strains from 11 species for biocontrol potential against Fusarium graminearum. The dataset includes results from co-culture assays, antifungal filtrate tests, molecular characterization of antimicrobial genes, and whole-genome analyses of ten selected strains. It is published on figshare under a CC-BY-4.0 license.

Use Cases

• Identifying promising Bacillus strains for biocontrol product development based on reported up to 75% mycelial growth inhibition.
• Analyzing the genetic basis of antifungal activity based on the presence of genes for compounds like fengycin and surfactin.
• Comparing the secondary metabolite gene cluster profiles of different Bacillus species, with B. velezensis noted for having the richest profiles.
• Screening for strains that reduce mycotoxin production based on results showing up to 100% reduction in deoxynivalenol (DON).

Strengths

• Includes whole-genome analyses for ten selected strains, revealing 15 to 24 secondary metabolite gene clusters per strain.
• Reports quantitative antagonistic activity results, with up to 75% mycelial growth inhibition observed.
• Molecular characterization confirms the presence of genes for specific antimicrobial compounds like bacillomycin D and bacilysin across all strains.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small in scale at 406.9 KB, indicating limited raw data volume.
