Raman Spectra of Cnm-Positive Streptococcus Mutans Bacteria and Biofilms

Giuseppe Pezzotti published a Raman spectroscopic analysis on April 27, 2026, comparing Cnm-positive and Cnm-negative Streptococcus mutans bacteria and their biofilms. The dataset, shared on figshare, contains spectral signatures aimed at revealing molecular origins of enhanced virulence and endothelial tissue damage. The file is a 95.5 KB DOCX document.

Use Cases

• Identify molecular differences between bacterial strains based on Raman spectral signatures described in the study.
• Analyze sulfur chemistry and peptidoglycan structure in Cnm-positive strains as suggested by the spectral features.
• Study adaptive resource allocation in bacteria based on described glycogen production and storage capacity.
• Compare biofilm adhesion properties versus strength based on described glucan production ratios.

Strengths

• Dataset is openly licensed under CC-BY-4.0.
• Description provides specific molecular insights, such as signals from residual oxysulfur molecules and differences in glucan production.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 95.5 KB, indicating limited scope.
