Background An environmentally abundant anoxygenic purple sulfur bacterium occurring not only in pelagic communities but also in littoral sediments like sandy beaches, salt marches and intertidal mud flats; this strain was isolated from ditch water. It is anoxygenically photosynthetic, and depends on reduced inorganic sulfur compounds originating from anaerobic degradation of organic carbon and concomitant sulfide production by sulfate- and sulfur-reducing bacteria. The reducing equivalents in sulfide therefore ultimately stem from carbon already fixed by oxygenic photosynthesis and capture of light energy by anoxygenic photosynthesis compensates for the loss of organic carbon in the anaerobic food chain. A. vinosum store sulfur globules inside of the cells when oxidizing sulfide or thiosulfate. They have this trait in common with a large number of environmentally important chemotrophic sulfur oxidizers like Beggiatoa and with sulfur-oxdizing bacterial symbionts of marine animals like Riftia pachyptila. On a biochemical level, oxidative sulfur metabolism of A. vinosum is among the best studied of all bacteria and the organism therefore already serves as a model for sulfur-storing bacteria. Purple sulfur bacteria fix carbon along the Calvin cycle. Dense accumulations of phototropic sulfur bacteria can feed organic carbon (which would otherwise be lost) into the carbon cycle of toxic water or sediment layers. The role of purple sulfur bacteria in these globally important processes has so far been largely underestimated and not been well studied (adapted from (EBI Integr8)
