Let’s Begin…
In the millions of years since oxygen began saturating Earth’s oceans and atmosphere, most organisms have evolved to rely on this gas. However, there are some places where oxygen-averse microorganisms like those from Earth’s earliest days have re-emerged. And one such place is hidden high in the Swiss Alp’s Piora Valley. Nicola Storelli and Daniele Zanzi dive into the depths of Lake Cadagno.
The pink anoxygenic phototroph Chromatium okenii—and more generally, the whole community of anaerobic microorganisms of the pink bacterial layer that forms in the chemocline zone—are very important for the ecology of the lake. Explain why. Can fish reach the anaerobic part of the lake and feed on the pink anoxygenic phototrophs?
