Inhibitory Activity of 397 Wine Yeasts Against Four Grape Fungi

Portuguese wine regions provided 397 yeast strains for a study of their biocontrol potential against common grape phytopathogenic fungi. The dataset, authored by Marcos Esteves and last updated in May 2026, contains results from time-course monitoring of mold growth inhibition. All tested yeasts displayed antagonistic activity against at least one of the four fungal targets: Aspergillus, Botrytis, Rhizopus, and Penicillium.

Use Cases

• Identify promising yeast strains for biocontrol based on reported strong inhibition percentages against specific fungi.
• Compare the efficacy of diffusible versus volatile compounds in fungal inhibition as described in the study.
• Analyze the relationship between yeast taxonomic affiliation and antagonistic activity against different mold targets.
• Screen for yeasts with a broad spectrum of activity based on the three strains identified as effective against all four fungi.

Strengths

• Includes results for 397 distinct yeast strains, providing a substantial sample size for analysis.
• Reports specific inhibition percentages: Rhizopus was strongly inhibited by 68% of strains, followed by Botrytis (20%), Aspergillus (19%), and Penicillium (7%).
• Distinguishes between two modes of action: inhibition by diffusible compounds and by volatile compounds.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific modeling tasks.
• The 51.5 KB file size suggests a limited scope, likely containing summary or aggregated results rather than raw experimental data.
