E. coli Growth in Human Gut Microbiomes from Anaerobic Microcosm Experiments

A 39.0 KB Excel dataset from a 2026 figshare upload by Mathilde Boumasmoud. It contains results from a reciprocal transplant experiment measuring the variable growth performance of Escherichia coli strains across different human gut microbiome samples. The data likely includes metrics on population growth, acidification effects, and the influence of specific resident microbes like Clostridium butyricum.

Use Cases

• Modeling interspecies competition based on E. coli growth variability across samples.
• Analyzing the impact of environmental acidification on bacterial population dynamics.
• Identifying keystone species, like Clostridium butyricum, that predictably alter community composition.
• Testing hypotheses about how intraspecific competition affects strain performance in diverse microbiomes.

Strengths

• Data originates from a controlled, replicated anaerobic microcosm experiment.
• Includes results from a reciprocal transplant design across multiple human microbiome samples.
• File is small (39.0 KB) and in a widely accessible XLSX format.
• Published 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 scale (39.0 KB) indicates a limited scope, likely containing summary or processed results rather than raw sequencing data.
