Assimilative Manganese Oxidation as a Tolerance Strategy in <i>Staphylococcus ureilyticus<

Lilia Montoya-Lorenzana's research dataset on figshare, last updated May 9, 2026, investigates manganese tolerance and oxidation in a novel bacterial isolate from the Gulf of Mexico. The 14.8 MB dataset includes PDF and TIFF files containing results from microbiological, microscopic, spectroscopic, genomic, and geochemical modeling techniques. It provides insights into microbial adaptations and potential roles in deep-sea manganese cycling.

Use Cases

• Study microbial manganese oxidation mechanisms based on described genetic pathways involving superoxide dismutase and peroxidases.
• Analyze biomineral formation based on scanning electron microscopy and energy-dispersive X-ray spectroscopy data confirming Mn-bearing precipitates.
• Model microbial tolerance to heavy metals based on the strain's demonstrated tolerance to Mn(II) concentrations up to 150 mM.
• Investigate reactive oxygen species-mediated oxidation pathways based on the proposed coupling of Mn(II) oxidation with cellular protection against oxidative stress.

Strengths

• Includes specific quantitative measurements: strain tolerance to Mn(II) concentrations up to 150 mM.
• Reports a measured oxidation rate range of 5.2–29.2 nM h⁻¹.
• Employs a multidisciplinary approach combining microbiological, microscopic, spectroscopic, genomic, and geochemical modeling techniques.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data files are in PDF and TIFF formats, which may require extraction or conversion for computational analysis.
