Yellowstone National Park

Caption: The image shows a hot spring in Yellowstone National Park, Montana, a site where bacteria containing chlorosomes can be found in the brightly colored mats. At the upper left is a thin-section electron micrograph of the green sulfur bacterium Chlorobaculum tepidum, showing chlorosomes along the periphery of the cells as light-colored ovals. The next image is an electron micrograph of an isolated chlorosome from the bchQRU mutant, and the next image is a cryo-electron micrograph of the same. Finally, the last panel at the right shows a molecular model of the chlorophylls in the chlorosome. Individual chlorophyll molecules are illustrated in green and show their hydrophobic tails pointing outward.
