Growing and testing gut microbes to restore a healthy microbiome
Official title: Designing a High-Throughput Platform to Bioprospect the Human Microbiome and ManipulateIts Iinterplay with Host Environments
Funded at Carnegie-Mellon University · NIH-11360439 · Data updated 2026-11-12
This project will build a lab system to grow many gut microbes so doctors can develop personalized microbe mixes to help people with gut, immune, heart, or memory problems.

Who could benefit from this research
✓Could help
People with conditions linked to gut dysbiosis—such as recurrent C. difficile infection, inflammatory or metabolic disorders, certain cardiovascular issues, or cognitive changes—would be the most likely future candidates.
✕Less likely to help
People without gut-related conditions or those seeking an immediate clinical treatment are unlikely to benefit now, because the work is primarily laboratory development rather than a therapy trial.
What this research studies
Researchers are creating tiny lab devices that can capture and grow many different gut bacteria, including species that are hard to culture today. They will use these devices to rebuild microbial communities and test combinations that could restore balance in the gut and support immune, metabolic, cardiovascular, and cognitive health. The team plans to work with microbes from human samples and reconstruct communities in controlled environments to learn which mixes are beneficial. The goal is to enable future personalized microbial therapies based on a patient’s own microbes or selected isolates.
Why it matters
Potential benefit: If successful, this could enable personalized microbial treatments that restore gut balance and help prevent or treat infections, inflammation, metabolic, cardiovascular, and cognitive problems.
How similar studies have gone: Related approaches like fecal microbiota transplant have helped C. difficile, but high-throughput culture of previously unculturable species and personalized reconstruction of communities is largely new.
