Line 7: [[File:Algae on left bacteria on right at Norris Geyser Basin in Yellowstone.JPG|thumb|250px|Thermophilic Organisms]] '''''Chloroflexus aurantiacus''''' is a [[Photosynthesis|photosynthetic]] [[bacterium]] isolated from hot springs, belonging to the [[ ==Physiology== As a genus, ''Chloroflexus'' spp. are filamentous anoxygenic phototrophic (FAP) organisms that utilize [[photosystem II|type II]] photosynthetic reaction centers containing [[bacteriochlorophyll]] ''a'' similar to the [[purple bacteria]], and light-harvesting [[chlorosome]]s containing bacteriochlorophyll ''c'' similar to [[green sulfur bacteria]] of the '' As the name implies, these anoxygenic phototrophs do not produce oxygen as a byproduct of photosynthesis, in contrast to oxygenic phototrophs such as [[cyanobacteria]], [[algae]], and higher [[plants]]. While oxygenic phototrophs use [[water]] as an [[electron donor]] for phototrophy, ''Chloroflexus'' uses reduced sulfur compounds such as [[hydrogen sulfide]], [[thiosulfate]], or elemental sulfur. This belies their obsolescent name '''green non-sulfur bacteria'''; however, ''Chloroflexus'' spp. can also utilize [[hydrogen]](H<sub>2</sub>) as a source of electrons.
