Abstract

Parvibaculum lavamentivorans DS-1(T) utilized the commercial surfactant linear alkylbenzenesulfonate (LAS) (20 congeners with C(10) to C(13) side chains) as a carbon and energy source by shortening the side chain, and sulfophenylcarboxylates (SPCs) and similar compounds (e.g., alpha,beta-unsaturated SPCs [SPC-2Hs]) were excreted with quantitative recovery of the sulfophenyl moiety. 2-(4-Sulfophenyl)decane (2-C10-LAS) was converted largely to 3-(4-sulfophenyl)butyrate (3-C4-SPC), as were 2-C12-LAS and 2-C14-LAS; the other products were 5-C6-SPC (SPC+2C) and 3-C4-SPC-2H. 2-C11-LAS was converted largely to 4-C5-SPC with the corresponding SPC+2C and SPC-2H; similarly, 3-C12-LAS yielded 4-C6-SPC with the corresponding SPC+2C and SPC-2H. 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. ...Continue Reading
