Gene Expression and Biofilm Data for Phaeobacter Probiotic Activity

Data supporting a study on the probiotic activity of Phaeobacter piscinae S26 against Vibrio anguillarum. The dataset includes measurements of tropodithietic acid biosynthesis gene expression under different biofilm conditions and surface materials. It was authored by Xavier Ferrer Florensa and last updated on 2026-05-12.

Use Cases

• Analyze the relationship between biofilm formation and antimicrobial gene expression based on GFP reporter and flow cytometry data.
• Compare bacterial attachment and mature biovolume across different surface materials like PDMS, PMMA, COC, and PP.
• Model the antagonistic response of Phaeobacter biofilms to Vibrio anguillarum based on biovolume and gene expression changes.
• Evaluate the potential of surface properties to enhance probiotic efficacy for aquaculture applications.

Strengths

• Includes quantified gene expression data showing a two-fold higher expression in biofilms compared to planktonic cells.
• Provides comparative biofilm formation data across four different surface materials, with PDMS showing ~30-fold higher early attachment.
• Contains results from a co-culture experiment showing Vibrio anguillarum counts reduced from 10^8 CFU/ml to 10^5 CFU/ml.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
