Probiotic Bacteria from Tribal Gut Microbiomes in Tamil Nadu, India

Supplementary file 1 contains data on 112 microbial isolates from stool samples of 25 healthy individuals from the Mulluvadi tribal community in Tamil Nadu, India. The dataset, authored by G. R. Shree Kumari and last updated in May 2026, focuses on 13 shortlisted bacterial strains evaluated for probiotic properties and postbiotic-producing potential.

Use Cases

• Evaluate probiotic strain survival based on tolerance to gastrointestinal stress conditions (pH, bile salts, NaCl, temperature).
• Assess safety profiles of bacterial isolates based on non-haemolytic and DNase-negative attributes.
• Identify strains with high postbiotic potential based on short-chain fatty acid (SCFA) production and antibacterial activity.
• Screen for probiotic candidates based on cell surface hydrophobicity and auto-aggregation measurements.
• Compare functional potency between Lactiplantibacillus plantarum and Heyndrickxia coagulans strains.

Strengths

• Includes data on 112 microbial isolates from 25 individuals, providing a substantial sample base.
• 13 representative strains were functionally characterized across multiple criteria, including survival (>70%), hydrophobicity (60%-80%), and pathogen inhibition (12-25 mm).
• All isolates displayed safety profiles consistent with probiotics, being non-haemolytic and DNase-negative.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to a single tribal village in Tamil Nadu.
