Tiny Earth Chemistry Hub

The Tiny Earth Chemistry Hub (TECH) brings student-based discovery to new heights. TECH was established in 2018 at the Wisconsin Institute for Discovery as part of the “Science and Discovery” core of Tiny Earth. Multidisciplinary approaches allow TECH to go beyond what can be accomplished in one semester and move the network closer to discovering the next antibiotic.

TECH’s growing isolate collection includes nearly 3,000 strains from over 20 institutions. The diversity of soil environments, culture conditions, and isolates is a rich asset to TECH and its mission of antibiotic discovery. These isolates are evaluated and prioritized based on activity profiles, genomic, and metabolomic data and some are scaled up for structural elucidation.

The Tiny Earth Chemistry Hub always welcomes collaborators in its quest to discover novel antibiotic compounds. Get in touch today!

Quick Documents


The Tiny Earth Database holds records of soil samples, culture conditions, and inhibitory bacteria that have been isolated from all over the world and is critical for discovering new antibiotics.

It standardizes record keeping and allows information to be shared with the entire Tiny Earth network, including the Tiny Earth Chemistry Hub. The public-facing side of the database is used for genomic research, classroom studies, and more as students search for discovery patterns and novel compounds.

The Tiny Earth Chemistry Hub uses the Database for accurate record keeping, comparisons to previous activity and results, and will be used to share information with users in the future.
