Extraordinary physiology of polyphosphate-accumulating Beggiatoa mats suggests a key role for phosphate buffering in marine sediments

Abstract Filamentous sulfide-oxidizing Beggiatoa spp. are widespread in marine coastal environments and can achieve significant biomass because of their substantial size. Their ability to store phosphates in the polymerized form of polyphosphates makes them potentially key players in altering the phosphorus (P) cycle at the sediment-water interface. This study examined phosphate uptake and polyphosphate formation in a P starved culture of the Beggiatoa sp. 35Flor strain.
