Abstract Seventeen strains of phototrophic bacteria (4 strains of Chromatium spp., 2 strains of Thiocapsa sp., 4 strains of Ectothiorhodospira spp., 2 strains of Rhodopseudomonas sp., and 5 strains of Chlorobium spp.) have been grown in sulfide-limited continuous cultures to assess the affinity for sulfide. It was found that the affinity (calculated as the initial slope of the specific growth rate versus the concentration of sulfide) is higher in those phototrophic bacteria that deposit elemental sulfur outside the cells, than in those bacteria that store the sulfur inside the cells. A hypothesis is presented to explain this correlation.
