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

An analysis of six temperate bacteriophages isolated from Trentingrana natural whey starters. The dataset likely contains results from quantitative PCR and virion detection experiments measuring prophage induction under cheesemaking-related stresses like heat shock, lactic acid, and oxidative stress. The data was authored by Andrea Mancini and last updated on 2026-04-23.

Use Cases

• Modeling prophage induction dynamics based on stress type and intensity described in the study.
• Comparing phage-specific genomic responses to abiotic conditions like heat shock and nutrient limitation.
• Investigating the relationship between phage genome copy number and virion release under different stress exposures.

Strengths

• Data is derived from six isolated and classified temperate bacteriophages.
• Experiments tested induction under four specific abiotic stresses: heat shock, nutrient limitation, lactic acid, and oxidative stress.
• Dataset is openly licensed under CC-BY-4.0.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small at 121.6 KB, indicating a limited scope of results.
