A Novel Freshwater Anammox Species of Candidatus Loosdrechtia Thriving Under Dual Salinity

Metagenomic and metatranscriptomic data supporting the discovery of a novel freshwater anammox bacterium, Candidatus Loosdrechtia thiotolerans (HSAMX1). The dataset, authored by Wei Li and last updated in June 2026, details the organism's physiological and molecular responses to combined high salinity and sulfate stress. It is a 2.4 MB Excel file shared under a CC-BY-NC-4.0 license on figshare.

Use Cases

• Studying genetic adaptations to osmotic stress based on the description of activated ion export systems and osmoprotectant synthesis.
• Analyzing sulfide oxidation pathways in anammox bacteria based on the high expression of the sulfide:quinone oxidoreductase (SQR) gene.
• Investigating niche specialization in microbial communities based on the finding that the species emerged only under dual salinity and sulfate stress.
• Identifying candidate genes for engineering resilient wastewater treatment microbes based on the described molecular strategies.

Strengths

• Dataset is based on integrated metagenomic and metatranscriptomic analyses, suggesting a multi-omics approach.
• Includes specific quantitative stress conditions: 3% salinity and ~86 mM sulfate concentrations.
• Highlights a specific gene expression finding where HSAMX1 accounted for over 90% of total community SQR transcription.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• The 2.4 MB file size suggests a relatively small dataset, which may limit the scope of analysis.
• Data may reflect bias inherent to the specific experimental conditions and sample source described.
