Microbial Adaptations in Icy Moon Analog Environments from 16S rRNA Meta-Analysis

Sandra Gusi-Martínez's dataset presents a meta-analysis of publicly available 16S rRNA amplicon sequencing data from terrestrial ecosystems analogous to Icy Moons like Europa and Enceladus. The 41.9 KB XLSX file, last updated in April 2026, integrates diverse datasets to identify statistically significant microbial patterns. The analysis suggests depth, pH, and hypersalinity are key environmental drivers, with osmolytes and modified lipids as shared adaptive strategies.

Use Cases

• Identifying key environmental drivers for microbial taxa distribution based on depth, pH, and hypersalinity.
• Analyzing shared molecular adaptations like osmolyte and modified lipid production across different analog sites.
• Guiding future life detection efforts on Europa and Enceladus based on inferred terrestrial microbial patterns.
• Studying the ubiquitous presence of halophilic archaea in hypersaline icy moon analog environments.

Strengths

• Dataset integrates diverse 16S rRNA amplicon sequencing datasets into a single meta-analysis, allowing for broader conclusions.
• Analysis identified statistically significant patterns, such as osmolytes and modified lipids as a shared adaptive strategy.
• Released under a permissive CC-BY-4.0 license, facilitating reuse and sharing.

Limitations

• Row count and column-level documentation are unknown, which limits suitability assessment and requires field semantics to be inferred after download.
• The dataset is small at 41.9 KB, indicating a limited scope, likely containing summary or processed results rather than raw sequencing data.
