Mats of Beggiatoa spp. occur on the surface of organic rich, anoxic sediments, at the hypoxic/anoxic interface, and oxidize sulphides to sulphates. For example Bernhard et al. (2000) reported mats of Beggiatoa spp. on the surface of sediments at a depth of ca 600m, in which the oxygen concentration was < 1µM (ca 0.02 µl/l) in the top 2-3 cm of sediment and sulphide concentrations were >0.1 µM.
