| Abstract: | The enrichment and isolation in pure culture of a bacterium, identified as a strain of Desulfovibrio, able to release and reduce the sulfur of isethionate (2-hydroxyethanesulfonate) and other sulfonates to support anaerobic
respiratory growth, is described. The sulfonate moiety was the source of sulfur that served as the terminal electron acceptor,
while the carbon skeleton of isethionate functioned as an accessory electron donor for the reduction of sulfite. Cysteate
(alanine-3-sulfonate) and sulfoacetaldehyde (acetaldehyde-2-sulfonate) could also be used for anaerobic respiration, but many
other sulfonates could not. A survey of known sulfate-reducing bacteria revealed that some, but not all, strains tested could
utilize the sulfur of some sulfonates as terminal electron acceptor. Isethionate-grown cells of Desulfovibrio strain IC1 reduced sulfonate-sulfur in preference to that of sulfate; however, sulfate-grown cells reduced sulfate-sulfur
in preference to that of sulfonate.
