Sulfide oxidation and carbon fixation by the gutless clamSolemya reidi: an animal-bacteria symbiosis


Solemya reidi, a protobranch clam lacking a digestive system and found exclusively in habitats rich in hydrogen sulfide (HS−), contains high densities of gram-negative bacteria within certain cells (“bacteriocytes”) of its large gills (Fig. 1). These bacteria are proposed to be responsible for the capacity ofS. reidi to oxidize HS− (Fig. 2) and produce… (More)
