This pattern of products confirmed that LAS is degraded by omega-oxygenation and chain shortening through beta-oxidation. At least nine major SPCs were formed from commercial LAS. The novel isolates Comamonas testosteroni SPB-2 and KF-1 utilized 3-C4-SPC; Delftia acidovorans SPH-1 utilized 4-C6-SPC enantioselectively. The substrate-dependent oxygen uptake of whole cells of strain SPB-2 indicated that there was inducible oxygenation of 3-C4-SPC and of 4-sulfophenol in whole cells of the strains of C. testosteroni during growth with 3-C4-SPC or 4-sulfophenol. The degradative pathways apparently involved 4-sulfocatechol and 4-sulfocatechol 1,2-dioxygenase. Strain SPB-2 and strain DS-1(T) grew together in LAS-salts medium, and only seven of the nine major SPCs were recovered. Strain SPB-2 utilized 3-C4-SPC, 3-C5-SPC, and 3-C4-SPC-2H. Strain SPH-1 grew together with strain DS-1(T) in LAS-salts medium, and a different set of seven major SPCs was recovered. Strain SPH-1 utilized 4-C6-SPC, 4-C5-SPC, 4-C6-SPC-2H, and 4-C5-SPC-2H. A three-member community consisting of strains DS-1(T), SPB-2, and SPH-1 utilized four major SPCs. We inferred that this community mineralized the major SPCs derived from 8 of the 20 LAS congeners.</dcterms:abstract> </rdf:Description> </rdf:RDF>
