Biodiscovery of novel microbes from extreme environments.

Extremophiles are microbes that thrive in harsh environmental conditions - where temperatures can be as high as 120˚C, the pH can range from highly acidic to strongly alkaline, and there are elevated concentrations of salts and/or heavy metals.

The geothermal microbiology team at GNS Science has built a microbial culture collection of over 1500 extremophile strains from New Zealand’s unique geothermal and hydrothermal environments. Our microbial collection is being screened for bioactives, and we are exploring diverse commercial opportunities. As well as characterising selected strains, our collection continues to grow through ongoing biodiscovery.


We have isolated a large number of novel microbial isolates, many of which represent new species, genera or even phyla.
