context_page_description: Champagne Pool is a prominent geothermal feature within the Waiotapu geothermal area in the North Island of New Zealand. The terrestrial hot spring is located about 30 km southeast of Rotorua and about 50 km northeast of Taupo. The name Champagne Pool is derived from the abundant efflux of carbon dioxide, similar to a glass of bubbling champagne. The hot spring was formed 900 years ago by a hydrothermal eruption, which makes it in geological terms a relatively young system. Its crater is around 65 m in diameter with a maximum depth of approximately 62 m and is filled with an estimated volume of 50,000 m³ of geothermal fluid.
context_section_description: Although Champagne Pool is geochemically well characterised, few studies have addressed its role as a potential habitat for microbial life forms. H₂ and either CO₂ or O₂ would be available as metabolic energy sources for autotrophic growth of methanogenic or hydrogen-oxidising microorganisms. Culture-independent methods provided evidence for filamentous, coccoid and rod-shaped cell morphologies in the hot spring. Two novel bacteria and a novel archaeon have been successfully isolated from Champagne Pool. 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.
