Efficacy of Sanitizers Against E. coli Biofilms on Stainless Steel and Polyurethane

Experimental results evaluating the efficacy of chemical sanitizers against E. coli O157:H7 in single- and multi-species biofilms under wet and dry conditions. The dataset, authored by Kavitha Koti and last updated in March 2026, includes results from testing on stainless steel and thermoplastic polyurethane surfaces with biofilms aged up to 60 days. Sanitizer performance was measured with and without mechanical scrubbing, using ATP bioluminescence and log reduction values.

Use Cases

• Compare sanitizer efficacy (e.g., BioDestroy®, Quats, hydrogen peroxide) based on surface material and biofilm age mentioned in the description.
• Model the impact of mechanical scrubbing on organic residue removal based on ATP bioluminescence (RLU) values.
• Analyze pathogen survival in mixed-species biofilms containing Carnobacterium and Lactobacillus under different humidity conditions.
• Evaluate the resilience of spoilage bacteria like Pseudomonas aeruginosa based on temperature and surface type.

Strengths

• Explicitly tests up to 7 sanitizer types including BioDestroy®, quaternary ammonium compounds, and peroxyacetic acid.
• Reports specific log reductions (up to 7 log on stainless steel, up to 5.6 log on thermoplastic polyurethane).
• Includes concrete ATP bioluminescence results, showing RLU reduction from >14,000 to ~100–180 with scrubbing.
• Covers a defined experimental matrix: two surface materials, two temperatures, wet/dry conditions, and biofilm ages up to 60 days.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (28.4 KB), indicating limited scope, likely summary results rather than raw experimental data.
