| Abstract: | Secondaryn-alkyl sulfates (and secondary alkanols) prove to be degraded aerobically by aPseudomonas species (Ps. B-2) to carbon dioxide, water and sulfate. The proposed mechanism for the biodegradation proceeds via the alcohol → ketone → hydroxyketone → dione → aldehyde + acid. Consequently, two fatty acids are formed which are subsequently degraded by β-oxidation. This pathway requires the presence of molecular oxygen for the hydroxylation of the ketone. Attempts to isolate bacteria growing on secondary alcohols anaerobically were unsuccessful. |
