Genomic and Functional Analysis of Stress-Responsive Prophages in Lactobacillus helveticus

Six temperate bacteriophages from Trentingrana natural whey starters were analyzed for their response to cheesemaking-related stresses. The dataset likely contains quantitative PCR and virion detection data from experiments exposing Lactobacillus helveticus to heat shock, nutrient limitation, lactic acid, and oxidative stress. Author Andrea Mancini published the 313.4 KB Excel file on figshare in April 2026 under a CC-BY-4.0 license.

Use Cases

• Modeling prophage induction dynamics based on stress type and intensity described in the results.
• Comparing phage-specific genomic responses to heat shock, lactic acid, and oxidative stress mentioned in the study.
• Investigating the decoupling between phage genome replication and virion release under different abiotic conditions.
• Analyzing the functional role of prophages as modulators of microbial population stability in natural whey starters.

Strengths

• Data is derived from six isolated and classified temperate bacteriophages within the Caudoviricetes class.
• Experiments cover four distinct abiotic stress conditions relevant to dairy processing.
• Dataset is openly available under a permissive CC-BY-4.0 license.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset's 313.4 KB size indicates a limited scope, likely containing summary or processed results rather than raw sequencing reads.
