Data Sheet 1_Variations in deep-sea microbial composition and assembly mechanisms under di

Yap Trench sediments from 4,159–6,682 m depth were used to study microbial diversity under different cultivation pressures. The dataset, authored by Libo Yu and last updated in March 2026, captures 44–55% of original microbial diversity under high-pressure conditions, compared to 6–18% under atmospheric pressure. It provides insights into microbial co-occurrence patterns and assembly processes in extreme environments.

Use Cases

• Compare microbial diversity captured under high-pressure versus atmospheric cultivation conditions based on the described experimental results.
• Analyze co-occurrence network complexity and modularity in simulated deep-sea oligotrophic environments.
• Study the shift from stochastic to deterministic community assembly processes under high-pressure cultivation.
• Identify pressure-tolerant microbial groups like Proteobacteria that thrive under serial subculturing.

Strengths

• Data is derived from deep-sea sediment samples collected at precise depths ranging from 4,159 to 6,682 meters.
• Quantifies a significant difference in microbial diversity capture: 44–55% under high-pressure vs. 6–18% under atmospheric conditions.
• Released under a permissive CC-BY-4.0 license, allowing for broad reuse and adaptation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data file is a DOCX document (963.8 KB), which may require extraction or conversion for computational analysis.
