Space Biofilms: Pseudomonas aeruginosa Gene Expression on Six Materials in Microgravity

Pseudomonas aeruginosa biofilm formation was characterized at one, two, and three days of incubation over six different materials in the International Space Station. The Space Biofilms project, performed by NASA, contributes to understanding biofilm morphology and gene expression in microgravity with respect to ground controls. The dataset was last updated on March 13, 2026.

Use Cases

• Modeling biofilm growth dynamics based on incubation times of one, two, and three days.
• Comparing material resistance to biofilm attachment based on the six tested surfaces.
• Analyzing gene expression changes in microgravity compared to ground controls.
• Investigating the protective effects of biofilm extracellular matrix in spaceflight conditions.

Strengths

• Data originates from a controlled experiment on the International Space Station.
• Includes observations across three distinct time points (one, two, and three days).
• Compares biofilm behavior on six specific material surfaces.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided in a BIN file format, which may require specialized tools for access.
