Planktonic Shewanella oneidensis Electron Transfer Measurements via Plasmonic Nanocrystals

Replication Data for 'In Situ Optical Quantification of Extracellular Electron Transfer from Shewanella oneidensis using Plasmonic Metal Oxide Nanocrystals' by Austin Graham, harvested from the Texas Data Repository. The dataset likely contains optical extinction measurements and derived current generation data for quantifying electron transfer from planktonic bacterial cultures. It was last updated on March 18, —.

Use Cases

• Modeling electron transfer rate constants based on optical extinction data mentioned in the description.
• Differentiating metabolic states of Shewanella oneidensis based on quantified current generation.
• Comparing EET performance across genetic variants using data from knockout and inducible expression strains.
• Validating plasmonic nanocrystals as biosensors in native biological environments based on the experimental results.

Strengths

• Data quantifies current production ranging from 0.12 to 0.68 fA per cell for genetically engineered strains.
• Enables time-resolved quantification of electron flux from planktonic cell suspensions, addressing a limitation of biofilm-based methods.
• Method validated by differentiating starved and actively respiring cells and cells of varying genotype.

Limitations

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