Table 1_Microbial dynamics and metabolic activity during fish decay under aerobic and anae

Data from controlled fish decay experiments comparing aerobic and anaerobic conditions, authored by Maria A. Diaz-Mateus and last updated in April 2026. The dataset includes measurements of oxygen, pH, hydrogen sulfide, water chemistry, microbial community composition via 16S rRNA sequencing, predicted metabolic functions, and mineral precipitate identification. The file is a 35.8 KB Excel spreadsheet.

Use Cases

• Compare microbial community structure based on 16S rRNA gene sequencing data under different oxygen regimes.
• Analyze correlations between environmental conditions (O2, pH, H2S) and predicted metabolic functions from PICRUSt2.
• Study the formation of early mineral phases (e.g., magnesium phosphates, sodium sulfates) during decay.
• Model decay trajectories and organic matter oxidation (e.g., β-oxidation) versus fermentation pathways.

Strengths

• Data is derived from controlled experiments with explicit aerobic and anaerobic treatments.
• Includes multi-modal measurements: physicochemical (O2, pH, H2S), water chemistry, microbial sequencing, and mineralogical (SEM-EDS, XRD) data.
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• Row count and column-level documentation are unknown, requiring manual inspection after download.
• The dataset is small (35.8 KB), indicating limited scope or a summary table rather than raw sequencing reads.
• Freshness should be verified as the last update date is in the future (2026-04-16).
