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 shared as a 3.1 MB XLSX file on figshare under a CC-BY-NC-4.0 license.

Use Cases

• Studying genetic adaptations to osmotic stress based on the described 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 stress-tolerant anammox bacteria for wastewater treatment applications.

Strengths

• Includes integrated metagenomic and metatranscriptomic analyses, providing both genetic potential and expression data.
• Documents a novel species that dominated under specific dual-stress conditions of 3% salinity and ~86 mM sulfate.
• The SQR gene from the novel species accounted for over 90% of total community SQR transcription, a specific quantitative finding.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
