Geobacter Sulfurreducens Evolution Data from 17-Year Bioelectrochemical Experiment

17 years of continuous cultivation on graphite anodes drove genomic and transcriptomic adaptations in Geobacter sulfurreducens strain KN400. The dataset includes comparative genomic analysis and quantitative transcriptomics data from isolates recovered after long-term adaptation. It was authored by Dawn E. Holmes and shared under a CC-BY-4.0 license on figshare.

Use Cases

• Study genome reduction and genetic drift in microbes under relaxed selective pressure based on comparative genomic analysis.
• Analyze regulatory remodeling for enhanced extracellular electron transfer based on transcriptomic data for pilA, omcZ, and omcB.
• Model biofilm-based electron transfer optimization based on crystal violet assay results for surface-associated biomass.
• Investigate mutations in c-type cytochromes and signal transduction proteins linked to enhanced Fe(III) oxide reduction.

Strengths

• Data captures a unique 17-year longitudinal evolution experiment.
• Includes multiple data layers: comparative genomics, transcriptomics, and phenotypic assays.
• Focuses on Geobacter sulfurreducens KN400, a model organism known for high current densities.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 14.4 MB file size suggests the dataset is relatively small in scale.
