Champagne Pool

The hot spring was formed 900 years ago by a hydrothermal eruption,[1] which makes it in geological terms a relatively young system.

[4] The siliceous geothermal fluid is oversaturated with metalloid compounds such as orpiment (As2S3) and stibnite (Sb2S3), which precipitate and form orange subaqueous deposits.

Although Champagne Pool is geochemically well characterised, few studies have addressed its role as a potential habitat for microbial life forms.

Culture-independent methods provided evidence for filamentous, coccoid, and rod-shaped cell morphologies in the hot spring.

[8] Bacterial isolate CP.B2 named Venenivibrio stagnispumantis tolerates relatively high concentrations of arsenic and antimony compounds and represents a novel genus and species within the order Aquificales.
