Algal Organic Matter Decomposition and Nitrogen Transformations in Lake Sediments

88.9 KB of experimental data from a short-term algal decay incubation study. The dataset includes results from spectroscopic, mass spectrometric, and metagenomic analyses, showing the release of proteins (8.36%), lipids (8.22%), and carbohydrates (7.72%) and their impact on nitrogen cycling. It was authored by Huaji Liu and last updated on 2026-04-11.

Use Cases

• Modeling nitrogen transformation rates based on the reported 88.7% reduction in nitrification and 34.5% reduction in denitrification under anaerobic conditions.
• Analyzing the temporal progression of algal organic matter composition based on the described three-stage release of labile, semilabile, and humic-like components.
• Investigating microbial interactions with organic matter based on the metagenomic analyses mentioned in the description.
• Studying the priming effect on sediment mineralization based on the high bioavailability of labile AOM described.

Strengths

• Data is derived from multiple analytical techniques, including spectroscopy, mass spectrometry, and metagenomics.
• Provides specific quantitative measurements, such as protein (8.36%), lipid (8.22%), and carbohydrate (7.72%) content in labile AOM.
• Reports clear temporal dynamics across three defined stages of decomposition (1 day, 3–7 days, >7 days).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset's 88.9 KB size suggests a limited scope, likely containing summary or processed results rather than raw instrument data.
