Enrichment cultures from river sediments yielded several non‐fermentative denitrifying bacteria, capable of anaerobic respiratory growth on the surfactant sodium dodecyl sulphate (SDS) as sole source of carbon and energy. Four selected isolates grew aerobically or anaerobically (with added nitrate) on primary alkyl sulphates of chain‐length C 6 ‐C 12 but not on the shorter homologues (C 2 ‐C 5 ), or dl ‐octan‐2‐yl sulphate, or sodium dodecyltriethoxy sulphate. Cell extracts from aerobic or anaerobic cultures of the most prolific isolate contained a single major inducible alkylsulphatase active towards octyl sulphate but inactive towards propyl, butyl, and pentyl sulphates, and secondary alkyl sulphates.
