Jim's black pool 在黃石公園中


也是首度有分離出 korarchaeota 的地方

溫度大致上在 63~97 度之間， pH 為中性

黑色的原因來自於黑曜岩的崩解

所以環境中充滿了 "矽" 以及 "iron sulfide"

This is a typical archaeal environment - Obsidian Pool in Yellowstone National Park. This is a neutral pH boiling hot spring, rich in silica and iron sulfide (pyrite). To us, this looks, and is, deadly inhospitable, but it is rich in archaeal (and bacterial) growth. It is a lot like a "black smoker" environment.
