The complete degradation of LAS is becoming better understood with pure cultures of bacteria

Research in two laboratories confirms the general belief that the complete aerobic degradation of commercial linear alkylbenzenesulphonated (LAS)involves communities and not single organisms. The community we postulate has a three-tier strucuture. The first tier involves the organism possessing enzyms for omega and partial beta oxidation of the alkyl chain in LAS molecules. The second tier organism converts sulfophenylcarboxylates (sc-SPC). The thire tier organism mineralises the formed sc-SPC via 4-sulfocatechol and ortho ring cleavage. This availability of pure culture should allow better understanding of the biochemistry and genetics involved in LAS degradation as well as of the interactions among the organisms involved.
