Abstract

Summary: An environmental isolate, strain ICD, utilized isethionate at concentrations up to at least 20 mM as carbon and energy source, with essentially quantitative sulfate accumulation. The initial step in isethionate metabolism is likely to be its oxidation to sulfoacetaldehyde since inducible sulfoacetaldehyde sulfo-lyase activity was demonstrated in isethionate-grown cells by assay and gel zymography; sulfoacetaldehyde itself did not induce the enzyme. Isethionate-grown cells of sp. ICD, unlike those of most other C-S bond-cleaving strains described, also contained an inducible sulfite-oxidizing activity. The results provide further evidence that sulfoacetaldehyde sulfo-lyase plays a central role in the mineralization of biogenic sulfonates.
