Fe(III)-Rich Basaltic Glass Dissolution Rates in Microbial Cultures

A 2026 study by Elena Yunda investigates the role of Fe(III)-reducing microorganisms in dissolving synthetic basaltic glass. The dataset likely contains dissolution rates measured over 7- and 15-day incubations with the archaeon Pyrobaculum islandicum and bacterium Thermus scotoductus, compared to abiotic controls. Surface alteration data from vertical scanning interferometry and Fe(III) reduction assay results are also likely included.

Use Cases

• Modeling microbial enhancement of mineral weathering based on measured dissolution rate multipliers.
• Analyzing surface alteration patterns on basaltic glass based on vertical scanning interferometry data.
• Comparing Fe(III) reduction rates between different microbial species based on assay results.
• Investigating the temporal evolution of dissolution processes based on 7-day versus 15-day incubation results.

Strengths

• Quantified dissolution rate enhancement (two-fold for Pyrobaculum islandicum in 7-day incubations).
• Includes data from controlled abiotic experiments for comparison.
• Surface alteration features characterized using vertical scanning interferometry.
• Released under a permissive CC-BY-4.0 license.

Limitations

• Dataset scale is small (1.7 MB), limiting the volume of underlying data.
• Row count and column-level documentation are unknown, requiring manual inspection after download.
• Data may reflect bias inherent to the specific laboratory conditions and synthetic glass used.
