Phylogeny and distribution of nitrate-storing Beggiatoa spp. in coastal marine sediments.

abstract：:The distribution of respiratory quinone electron carriers among cultivated organisms provides clues on both the taxonomy of their producers and the redox processes these are mediating. Our study of the quinone inventories of 25 archaeal species belonging to the phyla Eury-, Cren- and Thaumarchaeota facilitates their u...
