Acidophilic algae. Light micrograph of unicellular green algae ( Chlorella sp. ) from acidic soil surrounding a geyser. The soil the sample was collected from had a pH of between 2 and 4. Organisms can tolerate very acidic conditions either by adapting their proteins to be stable in such conditions or,more commonly,by evolving very efficient methods to pump protons from their cytoplasm. Sample collected from Norris Geyser Basin,Yellowstone National Park,Wyoming,USA | |
