	Chloroflexus aurantiacus - Wikipedia, the free encyclopedia
		Chloroflexus aurantiacus is a photosynthetic bacterium isolated from hot springs, belonging to the green non-sulfur bacteria.
		Chloroflexus aurantiacus has been of interest in the search for origins of the so-called type II photosynthetic reaction center.
		Thus, rare organisms like Chloroflexus aurantiacus that can survive using either respiration or photosynthesis are of interest in on-going attempts to trace the evolution of photosynthesis.

	chloroflexus (Site not responding. Last check: 2007-10-07)
		Chloroflexus is a anoxygenic, filamentous, gliding bacterium found in the green non-sulfur branch in the 16s rRNA tree of life (however, not all Chloroflexus are green and unable to use sulfide).
		Chloroflexus aurantiacus, which is a facultative aerobic species of Chloroflexus, can do anoxygenic photosynthesis that has characteristics of both green sulfur bacteria and purple bacteria (both of which are not closely related to Chloroflexus) as well as cellular respiration in aerobic environments.
		Chloroflexus is found at higher temperatures than other anoxygenic phototrophs with an optimal growth between 50 and 60 C (these temperatures found from growing the bacterium in a lab).

		Chloroflexus aurantiacus is important in studies addressing these topics.
		Chloroflexus is found at higher temperatures than any other anoxygenic phototroph.
		Chloroflexus grows primarily as a photoheterotroph and appears to consume the organic products of the autotrophic cyanobacteria in its native habitat.

		Chloroflexus aurantiacus is a bacteria naturally found in 70 C hot springs in Yellowstone and Japan.
		Research has shown that Chloroflexus aurantiacus is a thermophilic and photosynthetic bacteria that contains chlorosomes.
		For optimal growth of Chloroflexus aurantiacus in a laboratory setting, the bacteria needs to be kept in a one liter bottle of 'D' media, and a temperature of 50 C should be maintained.

		Chloroflexus aurantiacus and its phylogenetic relatives, which comprise a deeply branching kingdom-level lineage in the domain Bacteria (24), are major components of photosynthetic microbial mats in both sulfidic and nonsulfidic hot springs in Yellowstone National Park, Wyo.
		C of Chloroflexus lipids relative to cyanobacterial lipids in microbial mats pointed towards autotrophic growth of Chloroflexus-like organisms in hot-spring microbial mats (39).
		This confirms earlier observations of Chloroflexus photoautotrophy in these high-sulfide, Chloroflexus-dominated microbial mats (12, 39) and shows that carbon isotopic observations made in culture experiments can be extended to environmental settings.

		The relative simplicity of its reaction center and light- harvesting antenna systems make Chloroflexus an excellent model system for the study of photosynthetic energy capture and the genetic regulation and assembly of its photosynthetic apparatus.
		These isolated genes will be used for analyzing both the structure of the photosynthetic apparatus and its regulation of assembly.
		The exact mechanisms for this control have not yet been clarified, but it is clear that several photosynthetic components are under separate regulatory control.

		The moderate thermophilic, green gliding bacterium Chloroflexus aurantiacus contains two alleles for chaperonins
