Description:
Only five bacterial phyla with members capable of chlorophyll (Chl)-based phototrophy are presently known. Metagenomic data from the phototrophic microbial mats of alkaline siliceous hot springs in Yellowstone National Park revealed the existence of a distinctive bacteriochlorophyll (BChl)-synthesizing, phototrophic bacterium. A highly enriched culture of this bacterium grew photoheterotrophically, synthesized BChls a and c under oxic conditions, and had chlorosomes and type 1 reaction centers. "Candidatus Chloracidobacterium thermophilum" is a BChl-producing member of the poorly characterized phylum Acidobacteria.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bryant, Donald A -- Costas, Amaya M Garcia -- Maresca, Julia A -- Chew, Aline Gomez Maqueo -- Klatt, Christian G -- Bateson, Mary M -- Tallon, Luke J -- Hostetler, Jessica -- Nelson, William C -- Heidelberg, John F -- Ward, David M -- New York, N.Y. -- Science. 2007 Jul 27;317(5837):523-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biology, Pennsylvania State University, University Park, PA 16802, USA. dab14@psu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17656724" target="_blank"〉PubMed〈/a〉
